How many volts should a car’s battery hold?

A car’s battery is its life’s blood. With a good battery, the car starts easily. With a bad battery, the car does not start at all. The difference between having a good battery and a bad battery is a small measurement of voltage when the car is at rest or when it is running.

To accurately test your car’s battery you need a voltmeter and an assistant. A healthy battery should measure a charge of 12.6 volts when the car is off. When the car is running, the charge should measure somewhere between 13.7 volts and 14.7 volts. If your battery is maintaining these levels of charge when at rest or when running, then you know your battery is working properly.

If your voltmeter is giving you a charge level that varies from these levels, then bring your car to Doug Smith Kia in American Fork for a load test.
