How many volts does a car battery hold?

Most car batteries are labeled as 12 volts. However, they can hold closer to 15 volts due to power from the alternator. When the car is running and the alternator is charging, the voltage (electrical pressure) should measure between 13.7 to 14.7 volts. An actual reading of 12.4 volts when the car is running means that the battery is only at about 75% of its optimal capacity. Your car will still run, but you need to get the battery checked because it can be a sign that it needs to be replaced soon. If it falls below 10.5 volts, your car probably will not start, but some can go as low as 9.5 volts and still seem fine.
