12V Battery Voltage Chart: Understanding the Basics

Voltage Characteristics of 12V Batteries. Fully Charged: A fully charged 12V battery typically reads between 12.6 and 12.8 volts.; Nominal Voltage: The nominal voltage, or the average voltage during discharge, is around 12 volts.; Discharge Voltage: As the battery discharges, the voltage decreases, with 11.8 volts indicating a low state of charge and …

Battery Basics

Another disadvantage of recharging a lead acid battery at a fixed voltage of 13.6-volts is that once it is fully charged, 13.6 volts will cause considerable gassing and water loss. To prevent this from occurring the charging voltage must be reduced to 13.2-volts. The Charge Wizard will automatically select its STORAGE MODE of operation (13.2 ...
