*Take Lishen 2.6Ah 18650 cell as an example,
The battery cell should be stored in a dry (less than 70%RH) environment without corrosive gas. Do not let the battery cell bear any pressure, and there should be no condensed liquid attached to the surface of the battery cell. The best storage temperature is -20℃~20 for long-term storage. The battery cell must be in a charged 10%~35% SOC state, and voltage detection is required before use.
Storage period is less than 1 month: -20℃~60℃
Storage period is less than 3 months: -20℃~40℃
Storage period is more than 3 months-12 months: -20℃~20℃
