AGM Battery Charging Recommendations – Low Charge
The nominal voltage for an INDIAN MOTORCYCLE battery is 12.8 v when fully charged. The battery will self-discharge when disconnected from a vehicle, and will discharge at a faster rate when connected. If the battery voltage falls below 12.5 v, it should be charged immediately using the recommended battery charger.
Batteries which are not connected to a vehicle should be inspected every 2-3 months. The battery must be charged if found to be below 12.5 v.
Always use the recommended automatic battery charger, and wait for the charger to complete the charge cycle before disconnecting it.
