 Warnings:

  • DO NOT dissassemble the charger.
  • DO NOT charge other types of batteries beside the ones that are specified; improper use can cause explosion and breakage.
  • The charger is only for in-house use and should be kept away from heated surroundings.
  • Keep the charger away from humidity circumferences; no liquid is allowed to get in, otherwise it may cause damage and lead to accident.
  • Charger and Batteries should always be kept out of children's reach.
  • Charger may not be able to fully charge battery that has not been used for a long period of time; several recycles of charge-discharge will improve the battery's performance.
  • Please take battery out of charger after charging has completed to avoid battery self-discharge.
  • 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
  • Never leave battery un-attended when charging
  • We are not responsible 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
