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.
