Cautions:

  • Be careful when working with Li-ion cells - they are very sensitive to charging characteristics and may explode if mis-handled.
  • DO NOT charge other types of batteries beside the ones that are specified; improper use can cause explosion and breakage.
  • DO NOT disassemble the charger.
  • DO NOT put batteries on wood surface or carpet when charging; keep batteries & charger in a fire-proof container.
  • DO NOT leave battery un-attended when charging - please keep out of children's reach.
  • Keep charger & batteries away from humidity circumferences; no liquid is allowed to get in otherwise it may cause damage and lead to accident.
  • Please take battery out of charger after charging has completed to avoid battery self-discharge.
  • 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.
  • We are not responsible for damages if there is modification made to the battery's form, shape, or when made into packs.
  • User should have enough knowledge on Li-ion rechargeable batteries & charger before charging, discharging, and assemble.
  • We are not responsible for any damages caused by misuse or mishandling of these Li-ion batteries.
