How to Test Your Car Battery

Testing a car battery doesn't require anything more than a voltmeter. Follow this simple guide to see if your battery still has enough power to crank over the car engine.

Be certain the ignition key and the lights on the car are all turned off. Look to see if the battery terminals are clean or have some corrosion. If they are corroded, use a wire brush to clear the way for the voltmeter clamps. Attach the positive end of the voltmeter, usually red, to positive on the battery. Attach the negative end of the voltmeter, usually black, to negative battery terminal.

Look at the meter reading; anything over 12.4 is excellent, while anything under 12.2 is very bad. Disconnect the voltmeter clamps to your battery in the opposite way they were attached.
