Right Car Battery. Right Price.

Knowledge is power when it comes to your car battery and electrical system. The more you know about it, the less likely you are to get stuck. Your car’s electrical system consists of the battery, starter and alternator. The battery provides juice to the starter. Then, the alternator gives that battery the energy it needs to keep powering your car. If one of these parts isn’t working right, your car won’t start or run well. Our expert technicians can perform a complete check, and they'll help you understand just what’s going on with your vehicle’s battery and electrical system. If it’s time, they’ll take steps so your car runs better and stronger. After all, we’re the connection between care and the value of your car. Only available nights or weekends? No worries, since most stores keep hours that are convenient for you.

How Long Will Your Car Battery Last?

On average, an auto battery will last 3-to-5 years, but driving habits and exposure to extreme elements can shorten the life of your battery. At Firestone Complete Auto Care, we offer a free battery check with every visit to our store. This is a quick diagnostic check to determine your battery's health. It also gives you some idea how much car battery life you have left. That's right: one little test tells you if your battery is good to go.
