10. Usage Warnings & Precautions

Avoid short-circuiting the positive and negative terminals, as this may cause overheating or fire.
Do not overcharge (voltage >3.65V) or over-discharge (voltage <2.00V), as this can permanently damage the battery.
Prohibit reverse charging or exposure to mechanical shock, collision, or excessive pressure.
Use a qualified Battery Management System (BMS) to monitor and control voltage, current, and temperature.
Do not mix batteries with different part numbers in the same system.
Charging is prohibited below 0℃ or above 60℃; discharging is not allowed beyond -30℃ or 60℃.

11. Storage Guidelines

Short-term storage (1 month): Temperature -30℃~45℃, SOC 25%~40%, humidity ≤85%RH (no condensation).
Long-term storage (6 months): Temperature -20℃~35℃, SOC 25%~40%.
For storage exceeding 30 days, perform a full charge-discharge every 3 months to maintain capacity.

12. Warranty & Disclaimer

The battery must be used in accordance with this specification. Improper use may result in performance issues or safety risks, and no liability will be assumed for such cases.
Specifications and performance parameters are subject to change without prior notice. Users should confirm the latest details before use.
