READ MOREResting, fully charged 12-volt batteries read at around 12.8-12.9 volts. Counterintuitively, a battery is dead at 12.0 volts (not zero). The minute you apply a load to a battery at 12.0 volts, the voltage plummets and nothing happens. So, a reading of 12.4 volts on a resting battery means it''s about 50% charged. RV Battery Voltage Overview
READ MOREEventually, the battery will be "dead" and will need recharging. Note that a fully dead battery has 10.5 volts of resting charge. However, the minute you apply a load to it, the voltage plummets and nothing happens. Just remember that 12 volt batteries are not full at 12 volts and dead at zero.
