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 -20℃ 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 and adjust SOC to 25%~40%.
• Storage beyond 6 months without maintenance may cause capacity loss or cell defects.

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.
• This document is for reference only; actual performance depends on usage conditions.
