Indeed, we buy cell phone batteries should be very careful! Because the battery market, many of which are domestic mobile phone brand cell paste labels of various foreign sale, and then selling the goods as imports. So often people think that buy their imported batteries, but they were found to buy a new battery standby time better than buy a mobile phone battery attached to a long time. There was an example of such a person obviously buy original lithium battery imports, shorter than the original battery standby time 7-8 hours. Theory back to find stores, shops are irresponsible given the answer, with a bunch of jargon perfunctory. For example, excessive use of cell phone battery, charging is not correct, the phone too far away from the launch pad and so on. While these are all affect the power consumption, but the performance is very unlikely it so much worse! Therefore, in the purchase of mobile phone battery is best to find a credit, reliable store to buy a good reputation, it is not easy to lose. Pu Sanofi mobile phone batteries as the domestic brands, in this area is still very good.
Step 1


All products need in your home or using the battery. Add the size and type of batteries needed for each product. Some items including digital cameras use batteries, digital recorders, CD players, MP3 players, remote control, tools, flashlights, and children's toys.

(3) Note check the battery's shelf life, the recent purchase of the production of batteries, for those who do that by substituting the shelf life of batteries are generally difficult to identify the time of purchase, should be added to ask;
(4) Note check the battery appearance, without signs of leakage;
(5) shall be marked on the label manufacturer, battery polarity, the battery type, nominal voltage, trademarks, etc., should be looking to purchase alkaline batteries, or LR model or whether ALKALINE words.laptop battery Acer AC Adapters

How to store batteries?
There are generally inside the battery self-discharge phenomenon, commonly known as "run electricity", the battery storage time and temperature on the storage environment, especially have great influence, usually the longer the storage time, the higher the temperature, the battery "running power," the more ; the higher the temperature, humidity, the greater the conductivity of the battery contacts will rust and easy to use, and also increase the battery's "run electricity", so the battery storage conditions:
(1) Battery storage area should be clean, cool, ventilation;
(2) The temperature should be between 10 ~ 30 ℃, generally should not exceed 40 ℃; the relative humidity is generally not more than 65% is appropriate.

(3) is not easy too long storage time, storage should be arranged in neat rows, not the positive and negative connected to short-circuit the battery.


What precautions to use the battery?
(1) Check the electrical and battery contacts are clean, wipe with a damp cloth when necessary, to be dried into the correct polarity;
(2) Do not mix old and new batteries, the same model but different types of batteries can not be mixed;
(3) can not use heating, charging or other means to make a battery recycling;
(4) can not short-circuit the battery
(5) Do not disassemble the battery, do not heat the battery;toshiba AC Adapters Dell laptop keyboard
(6) electric appliances after use should be cut off at the beginning of long-term should not remove the battery.

Lithium Battery
Batteries used in laptops is the latest lithium battery, it can be used in notebook computers and mobile phones. And nickel-cadmium batteries, lithium batteries provide about twice the energy. Significant improvement in performance, while its price is three times more than nickel-cadmium batteries.

Most laptop computers to be fully charged for eight hours, but in general in the first four hours, they can charge a good 75% of the electricity, while the remaining 25% will take more time to go. The important point is to make sure the battery before charging the battery discharged. Most users use their laptop computers, will use a wall outlet, they rarely use the battery to the notebook computer power supply. So that your laptop has been stuck in power and there is nothing wrong in most new notebook computers, there is a sleep mode, it consumes very little energy. As long as you re-open the screen, will soon return to your last left off. If you plug in an external power supply laptop, you should look at the battery from time to time the release of energy. If you want to prepare two or three hours of continuous use laptop computers, best to unplug the battery until the battery power consumption, and then, and then plug it. On the other hand, if you do not use your laptop, put it on, the battery power runs out and then re-plug socket. At least a month to do so once or twice ACER travelmate 290 Battery ACER travelmate 2000 Battery ACER travelmate 800 Battery

Laptop battery material points by nickel-cadmium batteries, nickel hydrogen, lithium ion, such as several, lithium-ion battery charge and discharge require sophisticated protection circuitry, the production industry is relatively complex, lithium-ion battery production costs are higher.

Repair Methods:
First battery shell with a special tool called, and then investigate the reasons for the failure, it will test the good sorting welding up the battery, it is best to control board of the relevant parameters set up, debug and correct the shell will be sealed , this battery can normally use.
In the production of batteries, we use characteristics of U.S. imports of the batteries on the battery analyzer to screen analysis. The same group of cells required less than 1% tolerance, requiring each battery charge and discharge characteristic curves exactly the same, this step is most important, if done well, can cause various problems, such as the standby time is short, the ACER travelmate 230 Battery ACER travelmate 240 Battery ACER travelmate 250 Battery charge is not sufficient , can not function properly charging standby work, life is very short, charging out of the battery fluid corrosion notebook, or even cause an explosion or burning of entire computer battery vicious accident.

Do cell battery, be sure to use the special welding equipment, the general time of 0.02 seconds or less and battery within the weld connecting piece. Do not use hand soldering iron, otherwise it would cause cell performance decay or shorten the life span of a serious cause battery leakage or explosion.

Note that not enough manufacturers or different batches of the same manufacturer on the same batteries in a battery, or can cause a variety of possible failure.

After the restoration of the situation:
Appearance models will be nearly invisible most of the traces, a small number of models will leave a slight opening scene. Inherent power, the production of models for the two years ago, the general performance after the repair is not broke than when the battery is better, because it was mostly used in batteries is now out of the quality parameters, for example, in 1998 to produce energy-saving capacity of a single cell lithium batteries generally 1600mAH, and now the production capacity of the same type of products are 1800mAh, for recent models, the restored capacity of the battery is consistent with the original, the basic service life battery with the Original the same.ACER travelmate 3000 Battery ACER travelmate 5200 Battery 11 ACER travelmate 280 Battery 

 

Discharge of nickel-cadmium batteries are generally kept, because it involves issues of dendrite, cell body that may be dissolved at the crystal to blunt sharp at, causing a short circuit. The general charge for Ni-MH battery can be 40-50% of the electricity, hydrogen and water to prevent reaction. But not too filling, to prevent danger.

The following is an excerpt from a company related to storage: Storage
1. Studies show that Ni-MH battery charging state storage better than to keep the battery discharge state storage performance, so it is best to store the battery before charging the battery.
2. The battery short-term storage of not more than 3 months, the battery can be stored in -20 ℃ - +45 ℃, relative humidity 45% - 85% of the place and no corrosion, high temperature easily lead to battery leakage, reduce the battery performance, high humidity can lead to corrosion of metal parts battery.SONY VGP-BPS9A/B battery Sony VGP-BPS10 battery SONY VGP-BPL13 battery
Battery the best long-term storage maintained at an ambient temperature of -10 ℃ - +30 ℃. The long-term storage of the battery after initial use, the capacity may be lower than the store before, but after several charge and discharge, the battery can store before the resumption of the performance. If the battery is stored for more than six months, suggested at least six months, the battery charge-discharge treatment time.

After a long period of storage batteries, and battery has a natural discharge process, has the natural discharge is over, this does not affect battery capacity. The first charge, you should continuously charge the battery to 12 hours, and cycle to fully charge and discharge times (see the battery maintenance section) in order to wake up completely new battery, if this is not the battery is stored for a few months use, it is also recommended for three complete charge and discharge. If a battery by 12 consecutive hours after charge and discharge cycles, or three times still can not charge this battery can not be used needs to be replaced.
