The Correct Way to Safely Test Your Car's Battery

To test a car battery correctly, you'll need a few things like a voltmeter, work gloves, wire brush, and safety glasses. Be sure the car lights and engine are turned off, open the hood and use the wire brush to clean the terminals of the battery.

Take the red cable of the voltmeter and place on positive side of the car battery securely. Take the black cable of the voltmeter and place on negative side of the car battery securely.

Turn on the voltmeter, the reading will need to be at 12.4 or above for a good battery. Any reading at or below 12.2 is an indication the car battery may not be able to hold a strong charge any longer.

If you discover the car battery is weak, don't hesitate bringing your vehicle to Caspian Auto Motors so we can inspect the charging system and replace the battery if it is failing.
