1.To ensure that the battery maintains the capacity level, it is recommended that the battery and battery pack be stored at -0 ~ 35 ° C, low humidity, and non-corrosive gas.

2.Avoid storing the battery in high temperature or high humidity, otherwise it will cause battery leakage, rust, and low capacity.

3.Long-term storage may cause the capacity of the battery and battery pack to decrease, and it will take 1-3 charge / discharge cycles to reach the maximum discharge capacity.

4.The battery needs to be charged and discharged once after three months of storage. To avoid over-discharging the battery, it must be stored under power.

5.The battery is over-discharged for an instant and then charged immediately without damaging the battery. However, the battery will be damaged if it is discharged for a long time.
