How to Test Your Vehicle's Battery

At Mercedes-Benz of Arlington we want you to understand how your vehicle works and empower you to know simple service procedures like how to test your battery.

Using a Voltmeter

You can test the voltage of your battery with a simple voltmeter to get a pretty good understanding of if it's bad or good. Switch your voltmeter to measure voltage; then simply touch the negative and positive test probes to the negative and positive terminals on the battery when the car is turned off. If you get a reading of 12.4 volts or higher your battery is probably healthy. If the battery reads less than 12.4 volts then you might need a replacement battery.
