12 Volt Battery Voltage Chart
For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less. To get an accurate reading of a battery''s state of charge, you need to use a battery tester or multimeter that takes into account the battery''s type and voltage characteristics.
