Rechargeable Battery System Care to Extend the Life of Lithium-Ion Batteries:

WARNING: Do not use battery if you notice a change of shape (lumps), over-heat when charging or if rust or corrosion on the battery connectors is found.

  • Fully charge Lithium-Ion batteries before beginning to use the battery. Failure to charge battery prior to use will reduce battery life.
  • Keep Lithium-Ion batteries fully charged when not in use.
  • CHARGE BATTERY REGULARLY. Charge between each use and a minimum of once every few months. It is important to maintain at least 25% of your battery power when not in use. Failure to do this will result in performance problems and reduced battery life. Never leave Lithium-Ion batteries discharged for long. The batteries do self-discharge and the charge could drop low enough to damage the battery.
  • Avoid regularly running Lithium-Ion batteries completely dead.
  • The battery life is 300+ cycles before the battery will diminish in capacity output.
  • Lithium batteries provide a diminished capacity output at extreme cold temperatures - keep batteries inside the garment to minimize the impact and improve the performance.
  • Store Lithium-Ion batteries in a cool, dry place if you will not be using the battery for several weeks.
  • Keep Lithium-Ion batteries out of extreme temperatures. High temperatures may cause premature battery failure while lower temperatures can prevent batteries from fully charging.
