The polymer lithium battery itself has a certain life, which does not mean that it can be extended without use. The maintenance only has corresponding standards during use.

　　1. Charging standard

　　The charger of polymer lithium battery must be able to charge with constant current and voltage;

　　The single battery must be below 1C5A during charging;

　　The charging temperature range is 0~45 ℃;

　　The charging voltage shall not exceed 4.23V.

　　2. Discharge standard

　　Discharge current is less than 2C5A;

　　Discharge termination voltage of single battery shall not be less than 2.75V.

　　The discharge temperature range is - 20 ℃~60 ℃.

　　3. Storage standards

　　Batteries are generally flammable and explosive, and should be placed in a place that can avoid high temperature and be ventilated.

　　Long term storage environment of battery: - 20 ℃~35 ℃, relative humidity: 45%~75%.

　　The battery with a storage period of nearly one year shall be recharged to 10%~50% by standard charging method.
