Battery Charging Voltage Chart. When the battery is fully charged and the engine is ON the voltage is from 141 to 148 Volts. As a battery is charged the indicated voltage increases and as discharging occurs the indicated voltage decreases.
The first link is to the lowest voltage. Voltages and Specific Gravity are listed for a 6-volt or 12-volt battery and battery banks of 24 and 48 volts. The state-of-charge is how much charge is left within a single deep cycle battery or a solar battery bank.
If your battery is 6V or 24V divide by 2 or multiply by 2 proportionally.
The state-of-charge voltage varies slightly depending on the type of deep cycle battery being used. To enable screen reader support press CtrlAltZ To learn about keyboard shortcuts press Ctrlslash.
