The cells should be stored where it is cool, no light and away from heat sources and hazardous chemical. We also advise the cells should have 30%~50% of SOC. If possible, please charge the cells every three months. With proper storage and maintenance, the cells’ life can be prolonged.




  • Do not disassemble cells; Do not put cells in water or fire;
  • Please charge the cells with specified charger and follow the specifications. The cells can only be used in the specified equipment. It’s not allowed for other applications.
  • If the battery gives off an odor, generates heat, becomes discolored or deformed, or in any way appear abnormal during usage, recharging or storage, immediately remove it from the device or battery charger and stop using it.
  • Battery cell operating temperature shall be maintained below 40 for most of the time to keep a good battery life. The operating hours over 45 shall be limited within 100hrs/year.
  • Cell can’t be placed or used near fire or where it is over 60 or stored in such area.
  • Do not connect the positive (+) and negative (-) terminals with a metal object; Do not put the cells together with necklace, hairpin, coins or screws or other metal.
  • Please be careful and not damage the cells with sharp objects.
  • Please read the operation manual carefully. Any improper operation may lead to overheat, fire, explosion, damage or loss of capacity.
