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