Rechargeable Battery System Care:

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.

  • Failure to charge battery prior to use will reduce battery life.
  • CHARGE BATTERY REGULARLY. Charge between each use and a minimum of once every 3 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.
  • 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.

All 4 lights indicates the battery is charged, 3 lights indicate 75%, 2 lights indicate 50% , 1 light indicates 25% and flashing lights indicates the battery needs to be charged.
