The use of lithium batteries • Lithium battery charge up to the general meeting of 300-500. The best of lithium batteries partial discharge, but not discharge, and to try to avoid frequent fully discharged. Once the battery production line, the clock began to move. Whether or not you use the life of lithium batteries only in two to three years. Battery capacity is due to the decline of internal oxidation resistance increased (this is the battery capacity of the main reasons for the drop). Finally, the cell resistance will reach a certain point, although this time the battery is full of power, but batteries can release the stored electricity.

How to prevent aging lithium batteries If possible,try to charge the battery to 40% placed in a cool place.This will in the long term preservation of its own battery protection circuit operation.If the battery will be filled with electricity at high temperature,which will cause the battery tremendous damage.(When we use the fixed power,this time on full battery charge state,the temperature is generally between 25- 30C,and this can damage cells,which causes decreased capacity).

All in All 1.Avoid completely discharge,often of lithium rechargeable batteries.Repeated arbitrary will not damage the battery charger. 2.Lithium batteries will be placed in the shade, but not for cryosurgery.Avoid hot car.As long preserved,the battery charge to 40%after the placing. .3.If you use the majority of the time is fixed power,removed the battery under shady place.
