## What voltage should a fully charged motorcycle battery be?

Open circuit voltage for a fully, 100% charged AGM battery is 12.8 to 13.0 Volts. AGM batteries that are 75% to 100% charged will measure 12.5 to 12.8 volts. Conventional batteries have slightly lower open circuit Voltages: 12.6 volts (12.8 volts with Sulfate Stop) for 100% charge and 12.4 for 75% charge.

## What should a 12v motorcycle battery read when fully charged?

When a battery charger has been disconnected from the battery for one to two hours, a fully charged Conventional battery should read 12.6 volts (12.8 volts with Sulphate Stop) or higher.
