6 Battery storage and recharging
6.1 Battery storage requirements
1. Storage environment requirements:
–ambient temperature: -10℃...45℃; recommended storage temperature: 20℃...30℃;
–relative humidity: 0% 90%RH;
–in a dry, ventilated and clean place;
–no contact with corrosive organic solvents, gases and other substances;
–no direct sunlight;
–less than 2 meters from any heat source.
6.2 Storage expiration
In principle, it is not recommended to store the battery for a long time. Be sure to use it in time. The stored
batteries should be disposed according to the following requirements.
Required Storage Temperature
-10℃... +45℃
1.If a battery is deformed, broken or leaking, discard it immediately regardless of its storage time.
2.The allowable maximum stored battery recharging period is 3 years and the allowable maximum stored
battery recharging times is 3. For example, if recharging is performed once every 8 months, the allowable
maximum recharging times is 3 times; if recharging is performed once every 12 months, the allowable
maximum recharging times is 3 times; if the allowable maximum stored battery recharging period or times is
exceeded, it is recommended to discard the battery.
3. A lithium battery will have its capacity decreasing after being stored for a long time, and typically will have
its capacity irreversibly decreasing by 3%–10% after being stored at the recommended storage temperature
for 12 months. If the customer conducts the discharge test and acceptance according to the specification,
there is a risk that the battery with a capacity less than 100% after being stored will fail the test.
6.3 Inspection before battery recharging
Before recharging a battery, check its appearance: Deformation/Shell damage/Leakage
