Some places charge you for testing your car, but at AutoZone, it's free.
Don't buy a part you don't need. AutoZone will test your car's parts for free. We can test your car's battery, alternator*, starter* and voltage regulator* while they're still on your car. We can also give your car a complete starting and charging systems test. You can also take your alternator, starter or battery into our store and we'll test it. In most stores, we can also test voltage regulators, control modules, coils, throttle position sensors (TPSs) and other engine management components.
