  • Battery tested based on International Electrotechnical Commission (IEC) standard to ensure capacity, quality,and life time

Applications

  • Lighting or other device needs 3.7V power
  • Building portable power device that needs high energy density and low weight

Warning

  • CAUTION: when working with Li-ion cells, they are very sensitive to charging characteristics and may explode if mis-handled.
  • User should have enough knowledge on Li-Ion rechargeable batteries in charging, discharging,and assembly before use.
  • Put the batteries in fire-proof container
  • Do not put batteries on wood surface or carpet when charging
  • The battery is/are not suitable for e-cig mod.
  • Never leave battery un-attended when charging
  • We are not resopnsible for damage of any modification of the batteries in form, shape,or made into packs
  • We are not responsible for any damage caused by misuse or mishandling of these Li-Ion batteries
