5 Battery storage and recharging

5.1 Battery storage requirements

1. Storage environment requirements:
–Ambient temperature: 0℃~40℃; recommended storage temperature: 20℃~30℃;
–Relative humidity: 0%RH~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.

5.2 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.

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.
