6.1 Battery Storage Requirements
The battery is required to be stored in a temperature range from 0°C to +40°C. Routine maintenance is
required for batteries that have been stored for a long time. Depending on the storage time of the battery and
the storage environment, Please charge the battery to the corresponding SOC at 0.2C as required by the table
below.

After a long-time storage, the battery should be inspected and tested by professionals before use.
During the storage period, record temperature, humidity and storage environment in accordance with
storage requirements in this manual.
Long-term storage of batteries is not recommended, which will cause capacity loss. Generally, after 12
months of storage at the recommended storage temperature, an irreversible capacity loss of lithium
batteries is 3%~10%.
The batteries should be stored in accordance with the labels on the packaging box and should not be
inverted or placed sideways.
The battery boxes should be stacked according to the stacking requirements on the outer packaging.
When handling the battery, take care not to damage the battery.
Storage Environment Requirements
：
Ambient temperature: short-term storage (less than 1 month)0℃~40℃, long-term storage (more
than 1 month)5℃~35℃. Recommended storage temperature: 20℃~30℃.
Relative humidity: 5%RH~60%RH.
Store products in a dry, clean and ventilated place. Keep them away from dust, direct sunlight, rain,
vapor or groundwater.
Avoid contact with corrosive organic solvents, gases and other substances.
6.2 Charging Requirements After Over-discharge
The battery stops discharging there is still static power consumption of the internal battery module and its
own self-discharge loss, if there is no charge for a long time to replenish, it may lead to battery damage due to
over-discharge. When the battery SOC is low, it needs to be replenished according to the maximum interval in
the following table.
