WebDec 28, 2024 · A fully charged car battery voltage (without being plugged into an external device) ranges from 13.7 to 14.7 volts. It will drop to 12.4 volts when the charge is 75% and 12 volts when it is at 25%. A fully charged car battery voltage ranges from 13.7 to 14.7 volts, it will drop to 12.4 volts. Note:Battery voltages are temperature dependent. In fact, good charger systems (alt-energy systems) have temperature compensation built-in. The voltage data in the chart below is that of manufacturer spec. sheet listings (vicinity of room temperature). See more Note:Voltage measurements are only approximate to determine SOC. Measuring battery voltage is NOT the most accurate way to … See more Note:For best accuracy when measuring battery voltage, the battery must be in ‘open circuit’ condition (at rest, or ‘resting’). This means … See more Note:For longer battery life, lead acid batteries should remain in the green zone (40% or more SOC).
