1. The battery charger will indicate charge is complete by
illuminating the Green Charged LED .
2. If the battery charger is OFF, wake-up battery and meas-
ure the voltage across terminals. If voltage is above 28
Vdc, the battery is at or near full charge.
Where To Charge Batteries

servicing, all charging is done using the on-board charger.
The vehicle should be stored in a location within charging
temperature 0 to 45° °C (32 to 113° °F). The AC Power
