- Do not short-circuit the positive and negative terminals, as it may cause overheating or fire.
- Avoid overcharging (voltage >3.65V) or over-discharging (voltage <2.00V), which can damage the battery permanently.
- Do not reverse charge or expose to mechanical shock, collision, or pressure.
- Use a qualified Battery Management System (BMS) to monitor voltage, current, and temperature.
- Prohibit mixing with batteries of different part numbers or specifications.
- Do not charge at temperatures below 0℃ or above 60℃; avoid discharging beyond -20℃ or 60℃.
- Short-term storage (1 month): Temperature -30℃~45℃, SOC 25%~40%, humidity ≤85%RH (no condensation).
- Long-term storage (6 months): Temperature -30℃~35℃, SOC 25%~40%.
- For storage over 30 days, perform a full charge-discharge every 3 months and adjust SOC to 25%~40%.
