5 Battery storage and recharging
5.1 Battery storage requirements
1. Storage environment requirements:
•
Ambient temperature: 0°C ~ 40°C; recommended storage temperature: 20°C ~ 30°C.
•
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.
Table 5.2 Stored lithium battery recharging interval
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.
5.3 Inspection before battery recharging
Before recharging a battery, check its appearance: Deformation/Shell damage/Leakage.
