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.

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.

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.

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.
