Battery Voltage

Voltage refers to the amount of electrical potential your battery holds. The standard automotive battery in today’s vehicles is a 12-volt battery. Each battery has six cells, each with 2.1 volts at full charge. A car battery is considered fully charged at 12.6 volts or higher.

When the battery’s voltage drops, even a small amount, it makes a big difference in its performance.

Though not fully charged, a car battery is considered charged at 12.4 volts or higher. It is considered discharged at 12.39 volts or less.

12.6 volts = 100% charged battery
12.4 volts = 75% charged battery
12.2 volts = 50% charged battery
