Non-original laptop battery is largely composed of three parts: batteries, PCM plates, shell. Whether or not a piece of battery power is to look at the major and lasting batteries, so if you buy laptop battery, then first of all by its batteries ibm thinkpad r52 battery , ibm thinkpad t40 battery , are not imported, because the quality of imports is better, Then to look at its security, must be secondary protection, because the secondary protection is essentially to prevent the occurrence of an explosion, of course, this should be built on the batteries is no problem on the basis of the batteries if there are problems, then other things, no matter how well useless. There are batteries in the insulating material ibm thinkpad t41 battery , ibm thinkpad t41p battery , ibm thinkpad t42 battery is also very important, if the insulation failure, it is likely to lead to short-circuit batteries, so even if there is secondary protection, are more dangerous, so should be high temperature resistant insulating material, it is best not to fire until As for the battery is damaged. PCM board for example, is the most important procedures compatible with the computer, it needs to test the original notebook, however, higher costs for manufacturers, so manufacturers ibm thinkpad t42p battery , ibm thinkpad t43 battery , ibm thinkpad t43p battery generally will not do it. Best notebook battery casing materials have to be made by fire, so that only high temperature, the components inside of the battery also has a protective effect.

Friends of the phone to play the best configuration is the original mobile phone with original hp laptop battery, but many of the standard mobile phone battery manufacturers are often unique, such as Nokia, Motorola and so on. Perhaps a year ago, we all thought that a cell phone with two batteries it is sufficient. In fact, in particular the development of mobile phones, more and more, more and increase consumption of the new features in mobile phones, such as: TFT color screen, smart operating system, MP3, and so few megapixels, while the hp f2019 , hp f2019a , hp f2019b , hp omnibook 6000 battery battery capacity because of restrictions on the size of the phone can not function the same as several turned over, which caused less than battery capacity, so smart players will love for their machines with three or more of the battery, but the high cost of original equipment batteries, in particular, is an international brand, generally require Dayuan 150-500, which many users look prohibitive.Without concessions, at present, domestic mobile phone brand is the Scud batteries Jiaojiao industry, especially Scud batteries hp pavilion dv8000 battery , hp hstnn-db20 , hp 395789-001 , hp 396008-001 , hp pavilion dv9000 battery , hp ev087aa , hp ex942aa Collection of Business and is known as the second mobile phone original battery, as used in lithium batteries are imported, as well as advanced manufacturing process, so close to the original standby battery, and some even lead with original equipment batteries.
It is precisely because of the Scud batteries have become the first choice for today's public, so the market has resulted in a large number of counterfeit and poor quality of the Scud batteries, so that consumers have suffered loss. Now, I will introduce to you the author how to identify fake Scud batteries sony pcga-bp1n , sony pcga-bp2nx , sony pcga-bp2ny , sony pcga-bp2r , sony pcga-bp2s , after reading this article, I believe we can be much the same kind of election to their own satisfaction, rest assured that the Scud batteries.
We will package the following battery, battery and the internal structure of the appearance to tell us about the authenticity of the identification of mobile phone batteries Scud coup.
(A) of the battery package: Scud batteries have come into contact with people who will recall that the current level of Scud batteries pa2487u , pa3107u-1brs , pa3383u-1brs , pa3384u-1brs , pa3285u-1brs , pa3191u-1brs a total of 10 is divided into three series, as follows:
Business Blue Red Green Business Hongfei good move for China Olympic silver on the 1st pass easily SmarTone Bai Tong
1. Genuine middle Scud is a series of batteries used in a transparent glass box packaging, shell smooth and transparent, the overall color of uniform color card, clear handwriting. High-end business is the use of novel cell line absorption btp-43d1 , travelmate 220 battery , btp-58a1 , btp-60a1 , travelmate 240 battery , btp-52ew , btp-63d1 of the hard button plus carton packaging seals, battery positive and negative positions are transparent, and affixed to the back of the security code, as long as the scratch-coated, call 95105615 to find out the true battery Pseudo.
2. Counterfeit packaging cells are relatively rough, feel worse, rather more obscure fonts, the security code prompt inquiries for general also do not have this security code or have had inquiries. Therefore, this is the Scud batteries ASM 92P1140 , 40Y6795 , ASM 92P1132 , ASM 92P1130 , ASM 92P1128, FRU 92P1127 to identify the authenticity of a way.
(B) the appearance of cells: cell phone batteries are mainly to protect the plate and shell components, so get in the hands of a certain degree of texture.
Scud batteries overall appearance of smooth, smooth feel, logo integrity, are each marked with a battery dell inspiron 6400 battery , dell inspiron e1505 battery , dell gd761 model, the nominal voltage, rated capacity, and production date are negative, strict enforcement of GB / T 18287-2000 National Standard. Another unique security are: middle and low battery a laser anti-counterfeit stickers are standard, we can see light at the corresponding series of shadow text, such as: Red Scud can see "Scud" the words, and SmarTone Mobile Series can see that the "SmarTone" words ... business with the high-end series of products are affixed to the battery is the standard security polymer can see Scud the "SCUD" logo. Believe that the fake batteries to make this exhaustive might take some work better.
(C) the internal structure: the lawless elements to counterfeit brand-name battery is nothing more than profiteering, but only need to cut corners or use inferior parts, or on a non-profitable. Therefore, we simply open the battery dell inspiron 700m battery , dell inspiron 710m battery , dell f5136 , dell 312-0306 , dell 312-0305 shell, you can. (But if you do not identify this battery on the battery must be fake, or did not propose to take such a violent way, because if it is real power, it can not recover, it can not be returned. In addition It also has a certain degree of risk) after opening the battery, you can see the inside of the plate and protect the batteries, lithium batteries have a steel, aluminum shell and polymer division. Fake batteries generally failed to protect the plate or lithium batteries.
Knowledgeable than the current two bad fake Scud batteries: a plate there is no protection, the protection plate is used to prevent over charge and over-used in place, which is counterfeit batteries in order to save the cost of a commonly used means, usually Soft wire is connected to two batteries, these batteries dell inspiron 630m battery , dell inspiron 640m battery ,dell XPS M140 battery dell y9943 ,dell latitude d620 battery ,dell latitude d820 battery,dell Latitude D830 battery extremely dangerous, charging, the battery will usually have a high temperature, and then bulging batteries until the explosion. Another there is no batteries, is the use of button elements of counterfeit batteries to provide power, while some of the internal pad metal plates in order to achieve a certain weight, this battery is also known as "disposable batteries," the short life of qi.
The final selection for the forthcoming machine with love for their own players Scud batteries Suggestions: Scud batteries hp pp2100 , compaq presario r3000 battery , hp pavilion zv5000 battery , hp pavilion zv6000 battery must be bought to the store to buy the regular, but we must remember that to obtain an invoice or receipt, the battery immediately after the purchase of 95,105,615 for the authenticity of inquiries dial. I believe that love machine will also fall in love with Scud this "good food." -
1. In order to extend the battery life of lithium ibm laptop batteries in general charge time is not more than seven hours.2. The best use of purchase of the charger when the original manufacturers.3. Battery thinkpad t40 battery , thinkpad t41 battery , thinkpad t42 battery contacts with metal parts or contact with oil, pay attention to moisture.4. Do not dip the battery in water or thrown in the fire.5. Do not place the battery 08K8196 , 92p1102 , 92p1077 , 92p1073 , 08K8199 , 08K8198 , 08K8197 , 92p1075 is too low or too high temperature environment.6. For a change the battery, please apply to the use of mobile phone battery type.7. Rechargeable battery life is based on the cycle to calculate place and, therefore, adequate electricity, run out of electricity, to maximize battery life.Some cell phone maintenance of common sense 1. Clean mobile phones, use a damp cloth, or anti-static cloth. Do not use aspire 1410 battery ,travelmate 4500 battery , lcbtp03003 ,aspire 1300 battery , btp-apj1 , btp-aQj1 , btp-arj1 ,a42-a3 dry cloth (with electrostatic charge). 2. Do not phone / cell on the special high-temperature (60 degrees Celsius and above) Department, such as in the sun behind glass Department. 3. Do not use a cell phone antenna damage. Choice of mobile phones, only the election right.

Used to produce the rapid pulse charger is good, but for some of the dell laptop battery requirements of metamorphosis, such as the 1 hour fast charger, this time to adopt the ultra-high-speed greater than 1C charge current for charging the pulse method on the chew. Now the international community are using the basic pulse increases the response to the combination of polarization. In short, is based on the pulse, when the upper portion of a sine wave is completed, insert a short negative voltage cosine lcbtp03003 ,aspire 1300 battery , btp-apj1 , btp-aQj1 , btp-arj1 ,a42-a3 wave is too large to offset the enormous heat of the current (depolarization), thus the battery heat control. This approach generally more professional in the charger, such as the model used by professional players to use the charger. This type of charger can often 2C-3C with the current battery charge.
That these methods, from the point of view of battery life, slow constant-current charge is to ensure that the best way to battery btp-43d1 , travelmate 220 battery , btp-58a1 , btp-60a1 life. However, time is money point of view, the Quick Charger time savings benefits, than the injury about 10% of battery life is much greater losses. That is why very popular fast charger reasons.
Finally talk about the gum battery. Many MP3 players on the MD player that you do not you use gum battery, or else the two of us how to play the time will be so much worse.
This concept is wrong, gum battery is only a form of battery, in essence, is still the nickel-hydrogen batteries. In other words, the chewing gum a 1350MAH battery and one on the 5th of 1350MAH Ni-MH battery effect is the same player, there is no difference. In fact 5 of nickel-hydrogen batteries have appeared 1800MAH capacity btp-63d1 , btp-42c1 , btp-44a3 , btp-73e1 , batcl50l , travelmate 290 battery , travelmate 4000 battery battery far more than chewing gum. Batteries have a chewing gum is to the extent possible, equipment will be done Walkman thin, on the 5th battery specifications do not thin, and the specifications of the capacity of the battery on the 7th and Taiwan small, so small in Japan came up with this approach before, not because the gum battery capacity is particularly great. But there are gum battery thinkpad t40 battery , thinkpad t41 battery , thinkpad t42 battery nickel metal hydride and nickel cadmium distinction, early gum of nickel-cadmium batteries but only 600MAH, not present on the 7th largest 750MAH Ni-MH battery. -
Let me now do not look long-term preservation and restoration of the hp laptop battery method. Attention, and as a result of nickel-cadmium dell d5318 batteries and nickel-hydrogen batteries of different characteristics, so different leaf preservation. Nickel-cadmium battery is to run out to save electricity, so before you buy a new nickel-cadmium battery is a basic no electricity and need to reset their own. Generally speaking, the correct charging method used, is likely to take place 3-5 times in order to charge the dell latitude c610 battery , dell latitude c640 battery , dell 75uyf battery back to its best. And Ni-MH battery should be stored for a long time ago, should be recharged to 80% (this we should be counting their own), and then save. That is why now to buy a new nickel-metal hydride battery back somewhat after the electricity, because the manufacturers have pre-charge to prevent the transport turn-around time is too long, while the battery dell inspiron 6400 battery , dell inspiron e1505 battery is dead are affected. Long-term preservation of the nickel-metal hydride batteries, the first spent more than electricity, and then the right way to take charge 2-3 times can be restored to the best. (After dinner, and continue to! Ha ha)
Say that the issue on the charge. In fact, the most difficult to master is the correct charge. Charge from the charge current to points, a fast charge and slow charge difference. Judging from the charging method, there are constant-current charge dell latitude d620 battery ,dell latitude d820 battery,dell Latitude D830 battery and pulse charge the difference. A lot of people have this problem, what is good or slow filling fast good charge.
We first take a look at what is filling fast and slow what is necessary and sufficient. To a nominal battery capacity of 1C, the 0.1-0.2C in the charge current for the slow charge,> 0.2C charge for fast,> 0.8C for ultra-fast charging, <= 0.05C is the trickle charge . To the one 1400MAH Ni-MH battery as an example, the charge dell gd761 ,dell td347 ,dell KD476 ,dell Inspiron 1501 battery ,dell Inspiron XPS M170 battery , current between the 140MA-280MA for slow charge, and the same charge current of 280MA, on the one 700MAH rechargeable battery is that fast. This shows that the fast charge or slow charge is a relative concept, and the capacity of the battery itself has great relevance.
To return to the previous question, what is good or slow speed good? ! In fact, this is no fixed answer. Many people think that slow, and that will hurt the battery charge faster. Rechargeable battery fast will hurt you? The answer is yes, but not because a lot of people think the "harm to the battery charging current." High-current, at best, is an accomplice, the real reason is that fever, as a result of high current caused by fever. High temperature on the hp f2019 , hp f2019a , hp f2019b , hp omnibook 6000 battery life greatly. So nothing to be afraid of high-current, headache is how to solve the problem of heat.
Here, it is necessary to introduce a constant-current charge and pulse charge concept. When filling in the slow, basically all of the chargers are a constant current charging method, this circuit design is relatively simple, easy to implement. And because the scope of the charge current in slow and will not cause the problem of batteries compaq presario r3000 battery , hp pavilion zv5000 battery overheating. To the fast charge current issues, and then use the constant-current mode, no doubt can not avoid the issue of batteries overheating, so the constant current method was abandoned. Replaced by the pulse from the waveform can be seen on, the output charge current is not linear, but the sine wave. Peak, the current maximum, and then immediately into the trough, almost no current. The purpose of this design is to enable the battery to have a recovery time, thereby reducing the heat generated by high current, the battery heat control in an acceptable level. The market is now over a hundred million or so to see the rapid charger, the basic use of this method. But also uses this type hp pavilion dv8000 battery , hp hstnn-db20 , hp 395789-001 , hp 396008-001 , hp pavilion dv9000 battery , hp ev087aa , hp ex942aa of charger to determine the slope of the voltage or delta law judge to determine whether the battery is full, once a turn on the automatic trickle charge, over time in order to avoid high current damage to the battery. Comparison of well-known example is the co-users Jin Niu KN5060 recommended charger. The charger in the major electronic markets, the basic inter-scored in the 65-70, not very delicate work, but good results are highly cost-effective products. -
Members of the hp laptop battery you really do not know, there is a need for everyone to fill up classes. Nickel-hydrogen batteries have memory effect, but obviously did not nickel-cadmium batteries. The most obvious memory effect of a lithium dell KD476 ,dell Inspiron 1501 battery ,dell Inspiron XPS M170 battery battery. No memory effect means that can be recharged many times, and even spent on each charge without too much impact of fighting. Therefore the use of nickel-hydrogen batteries, they generally can not be considered a direct charge-discharge.
Of course, to extend the service life from the point of view, in the charging and discharging about 30-50 times, you can do a depth of discharge, to return to maximum capacity. AUDIOPHONE discharge is not as simple as that, and then a small hp 346970-001 , hp hstnn-db02 , hp hstnn-ub02 , hp dp390a , hp pp2100 light bulb until you can not light. Done so often over-discharge, rather than harm cells.
We all know that a nickel-metal hydride battery is rated voltage of 1.2V, at the time full power is more than the actual value, generally between 1.4-1.5V. With the use of voltage will gradually reduce, in general, the use of occasions, when the voltage is lower hp pm579a , hp pavilion dv4000 battery , hp pavilion ze2000 battery than 1V, it basically can not be used, for example, WALKMAN, CD DISKMAN, MD, MP3, DC and so on. You can test the "power run out," How much is the battery voltage.
However, if the occasion is the use of low-voltage, small current use will continue to discharge. We are talking generally refers to the depth of discharge voltage dropped to between 0.85V-0.9V. Through low-voltage, low current discharge, this value, the nickel-metal hydride batteries (including Ni-Cd) can be restored to the largest capacity, extend the service life. However, if it continues to discharge below 0.8V once may result in irreversible hp pavilion dv8000 battery , hp hstnn-db20 , hp 395789-001 , hp 396008-001 , hp pavilion dv9000 battery , hp ev087aa , hp ex942aa harm to the battery, but battery life has been affected. That is why the method AUDIOPHONE not be recommended, because you can not control voltage to a certain extent on the automatic cut-off value. Similarly, nickel-cadmium batteries and nickel-metal hydride batteries are not recommended for remote control like a small electrical current.
Depth of discharge of the battery is better to buy the charger have the discharge feature, or to a specific discharger. The easiest way is to AUDIOPHONE can, but must often read voltage value table, once to stop the hazardous sony vgp-bps10 , sony pcg-r505 , sony pcg-v505 , sony pcg-z505 area immediately. If it is connected in series, then the above simple battery voltage multiplied by the number of it. -
Buy electric car battery maintenance tips
2009-04-22
At present, the use of battery electric bicycle many varieties. In addition to using the most sealed valve-regulated lead-acid batteries, there are nickel-metal hydride batteries, nickel-cadmium batteries, lithium-ion batteries, lithium polymer batteries, zinc air batteries, fuel cells and so on. Among them, to the largest number of lead-acid batteries for. Minimum price for lead-acid batteries, but also the most commonly used, lead-acid batteries in China is the world's largest producer. Its composition with less pollution, better recyclability. The disadvantage is that small volume. In other words, in the same capacity, the battery weight and size are great. The current lead-acid battery is essentially a floating type of battery developed from. Float not meet the fast charge batteries and large current discharge, although the technical personnel to spend a lot of efforts have been fruitful to improve, you can enter the utility, but their life expectancy is still very unsatisfactory.
Specific volume of Ni-MH battery much better than lead-acid batteries, single and more battery life, and its high-current charge-discharge characteristics of lead-acid batteries than good. Ni-MH battery problem is to link up the battery pack more of the management issues, in the event of future charge-off, it will form a monomer melt partition the problem of battery, resulting in rapid battery failure group. Therefore, China's Ni-MH battery charger or the key technical issues and the battery management system, and this problem has not caused the various battery manufacturers and depots sufficient attention.
Therefore, the development of nickel-hydrogen batteries received a lot of constraints. Nickel-cadmium battery characteristics than current nickel-metal hydride batteries, and its characteristics of anti-Overcharge than nickel-hydrogen batteries, and China is the world's production of nickel-cadmium battery power. Some people raised the issue of cadmium, China is still a large number of exports to the European nickel-cadmium batteries and its application products, Europe to begin in 2006 restrictions.
To buy electric bicycle batteries, a product logo to see whether or not complete, including the manufacturer name, product specification model, the date of manufacture, trade marks; view is consistent both within and outside the mark, in particular, to check whether there was any eye-catching signs, production date in the near future should pay attention to whether . Second, we must pay attention to the appearance of the hp pavilion zd7000 battery , hp pp2182d , hp 338794-001 , hp pp2182l , hp 345027-001 , hp 342661-001 battery. See whether there was any deformation, cracks, scratches and signs of leakage. Battery terminals should be clean, no rust, should be clearly marked. The third is concerned about the electric vehicle battery rated capacity marked products. Marking the rated battery capacity of the larger, longer battery discharge, it is best not to buy non-rated battery mark, but should pay attention to electric vehicles for the exclusive use of any mark in more than capacity, rated capacity should be based. The fourth is to purchase well-known enterprises, large enterprises brand batteries. Batteries in general by a professional battery manufacturers to offer different brands, different battery manufacturers do not vary the quality, price is also divided into high and low. Well-known, large enterprises are large in scale, technology, and good after-sales service, the battery quality assured.
To extend the service life of electric vehicle batteries approach: First, it is necessary for electric vehicle lead-acid battery used in fear of loss of electricity, when the conditions, it is best taken immediately after stopping the power to add on, not every long-term once every 20-30 days, electric charge; second ride on his way to have run out of power if the feeling, do not wait to connect and use, the existence of micro-battery's power is the point of the security life pa3166u-1brs , pa3331u-1brs , pa3084u-1brs , pa3399u-1brs , pa3395u-1brs , pa3250u-1brs , pa3356u-1brs ,pa3291u-1brs battery power, if it continues to closed more than the use of life-saving power, great impact on battery life; three to the vehicle with the charger, the general features are floating, as long as the time for each charge within 12 hours of the basic battery are more advantages than disadvantages. As long as the attention of more than three points to ensure that you achieve the battery life good condition. -
The reporter learned from the city recently held a seminar that used batteries, battery consumption in Taiyuan City has more than 600 tons, the recovery rate is only 7%, more used batteries have not been properly addressed. Sanitation, environmental dell 310-6322 , dell d5318 ,dell g5266protection, as well as people from all walks of life have the initiative, hoping to find a used batteries to the "home" to reduce the harm to the environment.
Batteries will enable a one square meters of land barren, which contained lead, mercury, cadmium and other heavy metals will be a small number enter the body through a variety of ways, difficult to rule out the possibility of long-term savings, and damage to the nervous system, blood and bone function, or even cancer . After a long-term dell latitude c610 battery , dell latitude c640 battery , dell 75uyf mechanical wear and corrosion of the used batteries, the internal leakage of heavy metals and acid-base, soil and water may be contaminated.
April 2002, the city Sanitation Bureau of Waste Management began life on the battery dell inspiron 1100 battery , dell inspiron 5100 battery , dell 6t473 used to implement specific management Hotel in the sun, too much of a middle-iron recycling established, set up 173 recycling bins;in 10, 99 community placed 223 bins. To ensure that the heavy metals more button batteries and rechargeable battery recycling, but also in the studio, watch maintenance department set up 12 collection points, and with the Railway Administration, coal preparation plant and other large enterprises signed an agreement to take the way TM recovery. Nevertheless, compared with many cities, waste collection and disposal of batteries is still relatively small. It is estimated that the city more than 600 tons in battery dell latitude d620 battery ,dell latitude d820 battery,dell Latitude D830 battery consumption, but every year the number of recovery less than 40 tons, accounting for only 7% of the total consumption in each of the 560 tons of used batteries as a potential environmental pollution.
Low public awareness of environmental protection, lack of collection, turned over to the old battery scrap battery recycling consciousness is the main reason for the difficulty. Survey showed that 98% of the people are aware of its pollution, but only 11% of people will take the initiative to put recycling bins, the vast majority dell KD476 ,dell Inspiron 1501 battery ,dell Inspiron XPS M170 battery of people can throw away. During the interview, many people also said that relevant departments of the current lack of a powerful battery recycling is also one of the reasons for the measures.
At the seminar, many experts pointed out that the recycling of used batteries are not only from the environmental point of view, it is also profitable. Contains a large number of used batteries can be recycled, such as heavy metals and acid substances, 3,000 tons of used batteries can be recycled 141 tons of miscellaneous zinc ingots, metallurgy 300 tons of manganese dioxide, electrolytic zinc 181 tons, 500 tons of metal, which are valuable not renewable resources. At the same time, experts also introduced, household batteries hp 346970-001 , hp hstnn-db02 , hp hstnn-ub02 , hp dp390a , hp pp2100 now have basically reached a low mercury or mercury requirements, can be mixed with solid waste handling. The future is the focus of the collection of rechargeable batteries and button batteries, recovery mission has been to reduce the relative. In order to enhance the recovery rate, sanitation sector will be introduced to encourage the recovery of targeted policies, the establishment of the compensation mechanism for the recovery unit or individual of appropriate financial compensation. -
Nokia announced the recall despite the 46 million mobile phone batteries overheating, but industry experts pointed out that the lithium-ion battery is still the best, the safest choice.
Nokia announced that because of overheating risk, the global recall of 46 million mobile phone batteries btp-60a1 , travelmate 240 battery , btp-52ew , btp-63d1 . According to analysts expect the cost of the recall is expected to reach 500 million euros.
Although the number of 46 million is not small, but less than Nokia in the past 12 months sales of 1 / 2. Industry experts also acknowledged that lithium-ion battery is indeed a perfect space. However, lithium-ion batteries btp-44a3 , btp-73e1 , batcl50l , travelmate 290 battery on the release of early warning is still too early.
London, Ovum advisory body in charge of company's wireless business Martin Garner said: "From the engineering point of view, this is not a big problem. After all, the battery problem or a minority."
As a substitute for lithium-ion battery dell inspiron 710m battery , dell f5136 , dell 312-0306 , dell 312-0305 products, many companies are developing fuel cells. However, so far, easy to carry the fuel cell is less than the commercial standard.
Geoff Blaber analyst believes that in the next 12-18 months, this situation will not change much. Even to achieve commercial dell inspiron 4000 battery , dell inspiron 4100 battery , dell inspiron 2500 battery standards, then to spread to cell phones, but also take some time.
In addition, the latest invention of the fuel cell is not 100 percent safe. -
At present, the market for the three lithium batteries lithium polymer batteries, lithium-ion batteries and lithium metal batteries. And lithium metal batteries are the best, it has previously used nickel-cadmium, nickel metal hydride battery cells and the other two unmatched advantages. Lithium metal batteries 40Y6795 , ASM 92P1132 , ASM 92P1130 , ASM 92P1128, FRU 92P1127 due to the failure of a protective effect from abrupt fire from the electrochemical system and the special structure, with excellent security, almost without any kind of physical condition or adverse effects, including internal and external short circuit, overcharge discharge, overheating, such as extrusion.
Lithium metal batteries without memory effect, self-discharge rate of 1% -2% / month. Under normal room temperature to preserve and maintain their one-year 85% of capacity. The discharge curve of a flat evo n410c battery , evo n600c battery , evo n610c battery , evo n620c battery battery, it 250MA discharge rate, the output voltage from 3.3V when charging a short period of time (10 minutes) down to 2.8V, in the remaining 80% of the discharge time to maintain 2.8V, then decline termination of the 2V. This is undoubtedly beneficial for the cell phone battery. This battery provides continuous power supply when the current freshman to 2A. And nickel-metal hydride, nickel cadmium batteries for only 1-2 hours of talk time, a lithium metal battery powerbook g4 15inch ,a1012 ,a1079 , a1078 , a1148 capacity can be used continuously for 350 hours without charge. Its energy and weight up to 900 watt hours / kg, is lithium polymer batteries and lithium-ion battery 8-fold, so as to free rechargeable cell phone battery to create the conditions. -
Battery life is not determined by the length of time, but by the actual number of charge-discharge (not the number of statistical test software) to decide. If the battery is always loaded to the computer does not get down, removed AC power, because the environment in which lithium batteries is absolutely impossible for insulation, and battery control integrated circuit, so even shut down your computer when the battery power will gradually discharge. Again when connected to AC power, the battery 92p1102 , 92p1077 , 92p1073 , 08K8199 , 08K8198 , 08K8197 , 92p1075 will start charging (the battery is designed to power the majority of 95 percent in the beginning of the following charging, the battery design of different models are different), so when the power turned on or off, the battery will be recharged again and again and discharge. In addition, the computer at work will affect the heat is the battery life.
Therefore the use of the environment in the computer power supply stability, it is recommended that you remove the m8403 ,powerbook g4 battery , powerbook g4 15inch ,a1012 ,a1079 , a1078 , a1148 battery, power adapter and power supply alone. The purpose of this is very simple to avoid frequent battery fully discharged without being recharged. -
Activation of a new battery
10 does not require battery charge a few hours to activate the cell activity, in accordance with the normal charge-discharge-activated manner.
Proposed method: According to available data indicate that activation of the battery should be completed in the factory, the notebook battery dell inspiron 630m battery , dell inspiron 640m battery ,dell XPS M140 battery dell y9943 factory with a little electricity is the natural wear and tear in order to avoid damage to the battery. Should be activated battery protection circuit in the absence of circumstances, the circuit itself can be a lithium battery protection circuit, this circuit is designed in order to avoid over-charging and discharging batteries, general battery after full charge when the indicator goes out , non-rechargeable batteries into the power on, then you plug then plug the battery in the face of what to charge for? The situation from the battery on the battery will be able to see there is no charge, and teach you a simple way to determine the battery can be there in charge when the battery will heat the phenomenon, when an hour after the battery is full of (power do not pull the plug), you try the battery again to see if the battery does not heat hot? The results must be cold, because the state of battery charge and discharge is not of course, do not heat. Notebook manufacturers at the factory will be proposed that a new battery dell gd761 ,dell td347 ,dell KD476 ,dell Inspiron 1501 battery ,dell Inspiron XPS M170 battery ,for more than 10 hours. The author of this opinion is that notebook makers should take into account some new users to use a new battery when the charge does not fully grasp the skills, simply so that they charge 10 hours, so this should be the business of expediency.
How to charge
Most people that use automatic shutdown unnecessary re-charge, and do not charge quite arbitrary. Are generally used when the batteries need charging when the computer prompts further charge, of course, can be prompted to set the time, the default is to 3%.
The authors suggest that the majority of people with the method is the same as that. In fact, regardless of the notebook to use nickel-metal hydride or lithium batteries, these batteries have a memory effect is, the nickel-hydrogen batteriessony pcga-bp1n , sony pcga-bp2nx , sony pcga-bp2ny , sony pcga-bp2r , have a memory effect is obvious, but the lithium will have the same memory effect, but its memory effect than Ni-MH small number of them . On the memory effect of lithium is not only irresponsible exaggeration business advertising is completely misleading. Since then the battery has a memory effect when charging it should be noted that as far as possible and then run out of charge, but said there is no need to deliberate to the computer must automatically shut down, so did not use up what was so bad (because the notebook has a rechargeable battery discharge protection, automatic shutdown general notebook battery pa3383u-1brs , pa3384u-1brs , pa3285u-1brs has not yet reached the standard discharge protection), but you do not feel so tired? In fact, less than 3% charge on the good in this way, there will certainly be the memory effect than natural wear and tear, it should be nothing. As for saying that they want to charge on the charge of the point of view, the author is completely disagree, I have already mentioned the laptop battery, whether nickel or lithium hydroxide, which have a memory effect, so this way if the battery life will be significantly reduced.
Unplug the external power supply when the battery
Most people in the use of external power supply when the battery removed, only a small number of external battery pa3166u-1brs , pa3331u-1brs , pa3084u-1brs , pa3399u-1brs , pa3395u-1brs , pa3250u-1brs ,power is on the top of their brand names are used for several international brand names.
In fact, the battery is removed, the conflicts focused on the use of external power supply when the battery is charging up the issue. We should know that the number of battery charge and discharge is directly related to the life of lithium batteries in general set the number of charging and discharging are fixed number of charge cycles only 400-600 times, specially to improve the product but also 800 per charge on a battery40Y6795 , ASM 92P1132 , ASM 92P1130 , ASM 92P1128, FRU 92P1127 , a step forward to retirement. The first perspective is nothing more than fear of the use of power, the battery will be recharged on the top, not only increase the number of charge cycles and will have sufficient cause. The second view is that the battery is full power on the computer, in the use of external power supplies will not recharge.
In fact, both views have their right side, but also the wrong place. Because it is only the views expressed by individual people, not very comprehensive, after my investigation, many notebook manufacturers have to take into account the vulnerability of the battery and the product is added to the protection of the battery technology, and therefore the corresponding different brand notebook batteries charge of different protection technologies such as some large companies in this area is pretty good, such as: IBM, HP, Toshiba, Compaq,a1175 , a1185 , m8403 ,powerbook g4 battery , powerbook g4 15inch ,a1012 ,a1079 , a1078 , a1148, etc.. Which is considered the most thoughtful of IBM, IBM laptop battery discharge can detect the situation, ThinkPad notebook battery power only when less than 95% will be automatically recharged. This can play a very good protective effect of the battery, and now have quite a number of other manufacturers to follow. Therefore, the battery like this, you do not need to use when drawing down, because only when the power is lower than 95% of the time it will charge. Nevertheless, such a long time if you are using your computer, or the battery removed for better long-running notebook because of the heat generated would cause some harm to the battery. However, some other "little brand" notebook batteries, may not enjoy such treatment because it has not done inside the battery protection technology. I like to use a certain brand of notebook computers, if the battery btp-60a1 , travelmate 240 battery , btp-52ew , btp-63d1 , btp-42c1 , btp-44a3is full on top, in the use of external power supply must certainly recharged, because the battery will have a loss when stored, it is impossible to achieve 100%, and if not 100% , power supply connected to the charge. Each access to external power supply to the battery charge is equivalent to one, although only a small charge will be the time. It is proposed that all the time in the use of machinery in accordance with their own circumstances, notebook manual check, choose whether to use an external power supply the battery removed. -
Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: "depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life", I believe that this relatively one-sided.
To a correct understanding of this issue, start a notebook about the type of battery used. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a "memory effect", thereby reducing the battery's actual capacity, the elimination of this "memory effect" is the best way to repeatedly charge dell INSPIRON 2600 battery , dell INSPIRON 2650 battery . dell Inspiron 1300 battery and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the "memory effect" did not completely eliminate the shortcomings.
In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the "memory effect" problem, it is used repeatedly to restore the depth of battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery dell inspiron 630m battery , dell inspiron 640m battery ,dell XPS M140 battery dell y9943 ,in the built-in battery management systems.
Battery Management: At present, in notebook computers, almost all adopted the "battery management" and "charge-discharge control" of two chip-level management systems. The "battery management chip" placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery dell inspiron 1100 battery , dell inspiron 5100 battery , dell 6t473 built-in "chip control charge and discharge" the most important role is to monitor and control the battery charge and discharge the entire process and be documented.
Charge: Lithium-ion rechargeable battery the whole process is divided into "fast charge constant-current" and "reduced charge constant current" two stages. The so-called "constant current fast charge" means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the batterydell inspiron 700m battery , dell inspiron 710m battery , dell f5136 , dell 312-0306 , dell 312-0305 terminal voltage has reached the standard value, the controller will automatically turn into "reduced charge constant current" phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a battery charging process.
At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the battery's "charge-discharge control chip" of the memory. "Battery management chip" is through access to these data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.
Fixed: After repeated charging and discharging the battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time "battery management chip" has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh "charge-discharge control chip" memory of the data, thus ensuring the "battery hp 346970-001 , hp hstnn-db02 , hp hstnn-ub02 , hp dp390a , hp pp2100 ,management chips," the correctness of calculations.
A close look if you have the use of laptop manuals, will be found that "a month in the use of computer time, should make a full battery charge and discharge operation" note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and batteryhp pavilion zd7000 battery , hp pp2182d , hp 338794-001 , hp pp2182l , hp 345027-001 , hp 342661-001 nominal capacity and the actual situation, as a result the correct value of the battery capacity. -
Notebook batteries calculations
2009-04-15
At present, the majority of laptop batteries are based on industry-standard batteries, generally divided into two types of cylindrical and rectangular. Cylindrical batteries 08K8196 , 92p1102 , 92p1077 , 92p1073 , 08K8199 , 08K8198 , 08K8197 , 92p1075 ,thinkpad r60 battery , thinkpad t60 battery , 40y6797 , 40y6799 , fru 92p1139 , fru 92p1141 , fru 92p1137 ,than 5 bigger battery, and the square the size of batteries is roughly equivalent to the size of a Zippo lighter. At present, the mainstream capacity batteries: cylindrical for the 3.6 ~ 3.7V/2000 ~ 2200mAh, square for 3.6 ~ 3.7V/1800 ~ 2000mAh, so the number of batteries in the end the use of batteries, in accordance with the above figures to conclude that if the IBM ThinkPad T40/T41 standard battery 10.8V/4400mAh, then it is the number of batteries 6, using a three-string and the two methods, namely: the three core power in series to be 3 X 3.6V = 10.8V, the two series batteries after a further parallel to be 2 x 2200mAh = 4400mAh.
And the IBM ThinkPad T40/T41 increase the battery 10.8/6600mAh, then the batteries for 9, using a three-string and three-way, namely: the three core power in series to be 3 X 3.6V = 10.8V, the two groups series after the batteries pa2487u , pa3107u-1brs , pa3383u-1brs , pa3384u-1brs , pa3285u-1brs , pa3191u-1brs have been re-parallel 3 x 2200mAh = 6600mAh.
In general the greater the expansion of the battery cell and the difference between standards is an increase of the number of batteries in parallel to increase capacity. -
Misunderstanding 5: compatible battery charger can also use the
Notebook computer power than mobile phones, the most extreme circumstances, the power needs of battery charging at the same time and running at full speed to meet the required machine power supply, laptop charger compatible with the general no, because the various models of voltage, current, or even interface are different, can be common in a variety of notebook "compatible chargers are" likely to be of genuine more expensive than the charger,dell inspiron 1100 battery , dell inspiron 5100 battery , dell 6t473 even if the same interface, if the voltage and current below the nominal value of machinery, machinery working at full speed when the battery may not be able to obtain sufficient charge current, which damage the battery is a great one. If the voltage and current much less than the nominal value, or even find that simply can not boot or will boot but can not be recharged, so choose the best power to choose the time and the same original, it can not be found, please pay attention to a certain voltage and current machines to comply with the nominal values of the different products with the plant in general the same interface, hp pavilion dv2000 battery , hp hstnn-lb31 , hp ev088aa , hp 417066-001but the voltage and current may be different, we must pay attention to this point!
Misunderstanding 6: need fully charged battery (or put photovoltaic) preserved
Or whether it is full of light, in fact, is incorrect, put long-term preservation of photoelectric batteries will lose their activity and even lead to the control circuit protection self-locking and can not re-use, full of power will bring about long-term preservation of the safety problems, the most the preservation of the ideal way is to discharge to 40% and then save, lithium batteries are afraid humid and high temperature, it should be placed in a cool dry place to preserve, but the temperature not too low, otherwise the capacity will be greatly reduced, about 20 degrees Celsius is an ideal Storage Temperature.
Misunderstanding 7: battery dying, but also for its own batteries
The battery is a lot of people for such a deadly, manufacturers seem to expect someone to do so long ago, many brands of laptop batteries are designed to have self-locking function, once the batteries from the control circuit, the circuit enters a state of self-locking, Only the use of specific means to be answered, before the control circuit will not work, that is to say the same end-of-life battery, notebook battery batteries can not change the batteries, if you can not have to change batteries, please remember to find the specialized battery maintenance company to wield the sword, its own waste for just small, that after the failure of efforts to frustration and frustration is the worst.
Misunderstanding 7: 99% charge has been less than 100%, will continue to charge explosion
Notebook batteries almost no chance of explosion, the largest is the issue of high fever caused by melting of shell, but few give rise to fire, was released by a small number of incidents, the fact is that when the production technology of non-performing, leading to short-circuit in the use of a result, even if Most of this will be short-circuit the battery disconnect circuit protection circuit is not greater damage, unless it is in the protection of the circuit before the batteries armada m700 battery , evo n400c battery , evo n410c battery , evo n600c battery ,short-circuit (before the COMPAQ laptop battery explosion is caused by time should be), and such a thing in my notebook a large number of contacts over the past 3 years, have only seen two cases. It is such a thing in cell phones a lot, in the final analysis or the quality of the battery problem, a large number of poor-quality mobile phone battery assembly, and almost never on the laptop's battery did not sell, because there is no owner of a large amount of models that should be compatible battery production.
The reason why 99 percent to less than 100 percent after the charge is often because the record of the battery control circuitry and battery state of their own bias, the battery has not reached the record control circuit voltage, the power control circuit has been charging the battery in fact has been full of, such problems can usually be corrected through the solution, but even if there is no correction, because the majority of charging circuit will be filled in after a long time can not be disconnected automatically, thinkpad r51 battery , fru 08K8193 , 92p1060 , 08K8214 , 08K8195 ,and even automatically record wise 99% of the current set of 100 %, even the fool has been non-stop design, but also because of the current very small at this time and will not cause harm.
The current laptop batteries are basically the temperature detection circuit, when the battery temperature is too high, most of the control circuit will be forced off the battery to prevent further temperature rise, so this kind of charge to the explosion in the notebook computer battery occurred no less chance of the first prize in the lottery. -
Misunderstanding 1: the need for notebook computers bought three times repeated charge-discharge in order to activate the battery.
Unless you buy a notebook computer is more than one year of product inventory, or need not do so because there are batteries in the battery when the factory has been activated, and the batteries in the package when the battery into the notebook, after a equivalent to the activation of the test, so you get the battery in hand, already have been activated, and again three charge-discharge process was an increase in unnecessary depletion of the battery.
Misunderstanding 2: the first charge must be sufficient enough for 12 hours
This early stage those who do not have the battery control circuit of the Ni-MH battery models are applicable, but for now have a smart charging and discharging control circuit for the notebook battery is a joke, when the notebook computer battery is full, the charge current will be automatically cut off , even if you continue to charge 120 hours, there will not be any change in status, and generally speaking, even the slowest machine charge, hp pavilion dv8000 battery , hp hstnn-db20 ,6 hours when fully charged, the rest of the "charge" is just a waste of their time. It is time to get new machines should be first rechargeable battery.
Misunderstanding 3: the need for regular battery calibration, the total charge released once a month.
Strong memory effect for nickel-hydrogen batteries, which is an essential task, but for Li-ion battery, the cycle is too frequent, and lithium batteries does not completely eliminate the memory effect, but has greatly reduced the memory effect, if you use the battery is frequent, then you should discharge the battery to the relatively low (about 10 ~ 15%) re-charging, but even if the discharge to the open machines are not (0 ~ 1%), belong to the lithium batteries have greater depth of injury discharge generally every two months to do the operation once it. If you rarely use the battery, then every 3 months as long as the first such operation carried out on it.
Misunderstanding 4: correction to enhance the battery capacity can be
The so-called correction, when the actual capacity of the battery and control circuit capacity not the same as the record, the depth of a batterypa3383u-1brs , pa3384u-1brs , pa3285u-1brs , pa3191u-1brs charge and discharge operation, so that a record control circuit to the battery close to the actual situation, this is a true performance of the battery capacity rather than enhance the capacity of the operation, the key factor here is the actual capacity of the battery, if the actual battery capacity than the control circuit in the capacity to record high, correction can increase the battery capacity seems, if the actual battery capacity than the control circuit the capacity to record low, the correction will reduce the battery capacity seems also that many people debate the reasons for the effect of correction, keep in mind that correction is the true battery capacity is shown by the elimination of the battery and control circuit between the deviation, as demonstrated by the capacity will increase or decrease, this is the status of the battery itself, rather than corrected by your decision. Correction is likely because the batterya1175 , a1185 , m8403 discharge when the depth of injury, but a substantial reduction in capacity. -
March coincided with the peak season of solar photovoltaic industry to meet the critical moment, however, stocks are still digesting the impact of failure, although output has yet to see the demand reduction, inventory is still pressure to take food off of the solar battery factory orders, the recent pricing have been less than 2 U.S. dollars per watt, commonly known as the "iron price", highlights the market demand season is unknown.
The overall solar cell recently a considerable proportion of the transaction to less than 2 U.S. dollars-per-watt pricing, manufacturers in Taiwan from 1.9 to 2 dollars, and still growing proportion of lay-off appeared in the mainland solar battery factory 1.7-per-watt 2 U.S. dollars Price , explore the bottom line always scales more ferocious than the factory. One solar cell manufacturers the past two U.S. dollars accepted minimum "price of iron."There are companies that by the end of 2008, 2.1-per-watt is 2.2 U.S. dollars at the end of limit, no longer expected to maintain a steady downward bottom, otherwise, many enterprises have to face loss, and 2 U.S. dollars is a recognized "iron" iron board that the extent of economic slowdown fear serious than expected.
Experts point out that this wave of reaction of the market quotations may indeed have been worse than imagined, from the originally forecast in 2008 Q4 substantially since the beginning of the global battery factory production suspension could speed up the digestion inventory, orders in March are expected to be back to temperaturehp 417066-001, but the output still inventories are slow to digest, but not on dial-yun; prices fall, indicating the demand in 2009 may pessimistic than imagined, may have to rely on the Government's sudden adoption of a State subsidy strategysony pcga-bp2t, to change a negative situation; and the stability of hands unless the vendor orders, or by this wave of depression appears to not a small test.
Analysis of solar manufacturers, solar PV in March coincided with the peak season to off-season into a critical moment, in general, taking into account the installation of the system time, temperature in March is the main month of orders hp pp2100, however, the majority of solar photovoltaic manufacturers to that the visibility of orders in March is still low, mainly the European market has yet to rebound, demand is still a fine mist.
According to past experience that a stable price in February period, the beginning of March are approaching the peak season to enhance the impact of demand, prices have the opportunity to start up; however, in 2009 due to 2008 Q4 pressure environment factors, rapid decline in the price of solar cells , from the highest-per-watt 3.5 to 3.8 U.S. dollars to play early in 2009-per-watt 2.1 ~ 2.2 U.S. dollars, is now below floor plate price further. -
Laptop battery using mistakes
1999-11-30
Lives Longer In BIOS? - This is one of the few troubleshooting diagnostic tests you can do at home to find out if your laptop battery life problem is due to a hardware flaw or to the way the laptop is being operated. Enter the BIOS setup immediately after turning on the notebook on with a fully charged battery, usually by hitting the DEL key, the F1 or F2 key immediately after you power on. Some laptops display a text message telling you what key you need to hit to enter the BIOS setup, on others the message is suppressed by a BIOS setting, but you can always go online and Google the right key combination if it’s not in your manual. Once you bring up any BIOS screen, measure the time it takes the laptop battery to run down. If it doesn’t outlast the battery life under regular usage by a good margin, the short battery life is probably due to a faulty battery or a hardware failure that causes the laptop to continually suck power when it shouldn’t.
AC Adapter Noisy? For starters, this is one of those problems that tends to bother more women than men, because men lose their high frequency hearing at a much earlier age than women. Battery chargers typically include a transformer and some power IC’s, at least a bridge rectifier. There’s a lot of potential for humming and whistling with transformers, but they can go on operating that way for years without failing. If the battery charger gets very hot, then it’s time to check the manufacturer specs for temperature and see if it needs replacement, and check the dell Inspiron 6400 battery temperature as well. In all cases, the acoustic behavior of your AC power adapter and charger may naturally vary with the quality of the power from the utility, and the feed voltage if you are traveling. Anytime you can avoid running a computer on poorly regulated or intermittent utility power you should do so, but at least with a laptop you’re better off than with a desktop.
OS Battery Management Active? Older notebooks were equipped with hardware only battery management schemes that controlled both charging and battery operation. All new laptops ship with ACPI (Advanced Configuration Power Interface) which is a marriage between BIOS routines that monitor board level charging and device activity, and the operating system. The operating system power management comes equipped with a number of default profiles that instruct the laptop if and how to nurse the dell C1295 battery. There’s usually a power user profile that just runs full out with no consideration of battery life, a number of special purpose profiles, such as running a DVD movie for a sole task, and a miserly setting that cuts performance to a minimum and puts devices like the hard drive to sleep when not in frequent use.
You can micro-manage these profiles to suit your needs, and you can always go into the settings and override them or change the profile at any time. The most useful trick to remember for running on dell GD761 battery is how to brighten or dim the LCD screen using the the function screen. Screen brightness is a serious power drain (you’re essentially powering a small fluorescent lightbulb) and in most indoor usages, strategic choice of where you sit can add time to your battery life. When troubleshooting battery life issues, you may want to run a power management profile that doesn’t come up to your expectations for performance for a few battery cycles just to help diagnose the problem.
DC Voltage Good? Check the voltage at the output of your AC adapter with a DC voltmeter, right on the barrel connector that gets plugged into the laptop. The rule of thumb for acceptable readings on power adapter output is usually a 5% variation either way of the faceplate voltage, and in terms of charging a dell Inspiron 6000 battery, a high reading is better than a low reading. If you’ve purchased a lightweight battery charger for travel, don’t assume that it’s putting out the correct voltage just because there’s a connector that fit your notebook. Check your owners manual or the label on the original battery charger that came with the notebook.
LED For Charging Blink? While there’s no universal standard, a blinking LED on the battery charge indicator is probably not good news. It often indicates a battery that has been over-discharged, the voltage is so low that it’s confusing the charging circuitry into thinking the battery has a dead cell and would just overheat if a charge is pushed into it. The newer the laptop, the smarter the charging logic, and it won’t want to try putting a charge into a battery that may damage either the battery or the notebook itself. In some cases, you’ll be able to recharge an over depleted dell Inspiron E1405 battery if you wait until the notebook is shut down, install the battery, and then plug in the the battery charger, but I’d keep a close eye (and occasional finger) on it for overheating. There are also fuel gauges built into some newer batteries that simply disable the battery when it reaches it’s planned cycle life.
Does Battery Get Hot? Recently there have been a spate of high profile stories in the media about laptop batteries catching fire. This wasn’t caused by normal heating due to charging. The problem was in the manufacturing process of the individual cells, where apparently some contamination led to internal short circuits that could cause the battery to overheat even if it wasn’t in use. dell Inspiron E1505 battery normally heat up a little on charging, and they heat up even more when discharging under heavy demand. Battery packs usually include a temperature cut-off circuit, that will halt battery charging or discharging if it really overheats. In some cases, the battery will not be usable afterwards because the cut-off acts like a circuit breaker that can’t be easily reset.
It certainly doesn’t do your laptop battery any good to get very hot, even if it’s within the toleration of the protective circuitry, so if it’s overheating on discharge, consider running on AC power instead. Just remember you have to shut down before removing the dell Inspiron E1705 battery unless it’s specified as being hot-swapable:-) You can also try decreasing the performance settings to lower the power drain. If the battery is overheating on charging, you can try charging when the laptop is turned off since the laptop is generating heat as well. Also, pay attention to the ambient air temperature. All notebook computers depend on the ambient air for cooling, so unless you are running the computer on a special cooling pad, think twice about using it on those 110 degree days!
Latch Locks Tight? It’s impossible to see what’s going on with the connector contact inside the battery compartment once the battery is installed, so the only indicator you have to proper installation (aside from normal operation) is the condition of the latch. If the latching mechanism doesn’t show a positive close by clicking back to the relaxed position, try reinstalling the battery. Some laptops have a manual battery lock that is operating separately from the latches, and which will not lock unless the battery is installed properly. If the latches refuse to click closed on their own, remove the battery again, visually inspect for any bulging or distortions in the package, and check the connector for damage.
