How to maintain polymer batteries?

Many people think that the life of the polymer battery is the number of improving, in fact, it is strictly called the charging cycle. A complete charging cycle is charged 100% electricity, then put 100% electricity. Lithium battery life is probably 300-500 full charging cycles. The correct statement of lithium battery should be, 300-500 complete charge and discharge. That is, it is assumed that a 100% battery is used: 500%, charge 30%, which is not a complete cycle, a complete cycle is charged to two 100, this is actually 40% cycle, waiting for you to use 60% were charged 40%, and there were 90% of the cycle. Push .. Lithium electricity is no memory effect, so I agree with Apple's claim, the use of lithium battery - should be, use some, charge some, not charge too long, nor will it be used. Charging the battery, it is best to charge it with a small current, generally charged with 0.5c-2C, small current is irritating, and better maintenance of the battery. Avoid overcharge, generally set the charging cutoff voltage is: 4.25V, the discharge cutout voltage is: 3.0V, the cutoff voltage of the discharge, and according to the actual situation, avoid full storage. When not in use for a long time, the lithium battery should be removed, placed in a cool dry place. Do not refresh to avoid moisture erosion. Avoid use in a high temperature. For a long time, the battery is charged to 40%, or the voltage is stored between 3.75-3.85V. Now more and more devices support USB charging, personal feelings can not open, or the above reasons. However, USB charging, seeing a friend posted that because the voltage is insufficient, it is dissatisfied (PDA has not been encountered, it can be full, I don't know why 580 is not line), I have also encountered the same situation. Said from habit, don't want to plug in USB every time, you have to charge for a while, mainly a habit, so I am charging USB. If there is no power supply, it is possible to open it again, and it is convenient anyway. At the same time, I don't know if I have a non-standard voltage, I will not have an impact on my mobile phone and the battery. In the case of unknowing, I personally tend to turn off the USB charging as much as possible. The self-discharge ratio of the lithium polymer battery is still a bit high. Insurance, if not, it is best to be filled, then store it after the rubber bag is sealed. It is necessary to take it once in 1-2 months, that is, charge it, and keep the activity of lithium ions. Don't exceed 3 months old, you must take it out. It is not necessary to store too long, and the lithium ion activity will be lowered and the battery life is affected. In too hot or too cold, use lithium electricity, it also affects lithium battery, so in hot days, don't leave the phone in the car or sunlight; if the outside is less than 20 degrees, Don't take your mobile phone outside (for a long time), or put it in a warm pocket, use your headphones (not to use Bluetooth headsets, that is also lithium). Polymer lithium ion battery: The temperature range is from 0 to +45 ¡ã C during charging; the temperature range is from -20 to +60 ¡ã C; the battery is stored for long-term storage: temperature -20 ~ + 35 ¡ã C.
