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.

AutoZone can charge your battery for free while you wait.

We have a Duralast Fast Charger that can charge your battery for free while you wait. The fast charger charges 12-volt batteries in about 30 minutes. AutoZone also offers overnight battery charging for 6 or 12-volt lawn and garden, motorcycle and marine batteries.
