How To Test Your Car Battery


Is it time for a new car battery? It can be difficult to tell whether your battery simply needs charged or whether it’s no longer holding a charge. The easiest way to tell is to test your battery. Find out how you can enjoy free testing and learn how installing a top post car battery can restore your car’s power.

Getting AutoZones Free Battery Testing

Don’t replace a battery unless you’re sure it’s reached the end of its life. There are a few signs that your battery may be compromised. Locate your battery and look for any signs of corrosion or physical damage. Use caution, as a damaged battery may leak sulfuric acid. Any damage to the battery itself requires full replacement.

You may have an alternator issue if you don’t see any damage to the battery, particularly if it’s less than 5 years old. This means your auto battery is working properly, it just isn’t receiving a charge while your engine is running. In that case, you may need to have your alternator repaired or replaced.

The best way to know is to test your battery. Stop by a local AutoZone location for free battery testing services. Ask about this free service to enjoy a definitive answer about the state of your battery. This free test gives you a better understanding of the charge your battery can hold.

Start by turning the ignition and your headlights off. An AutoZone technician will use a professional device to test the battery itself. This will give a reading that states whether the battery is charged or not and whether it’s reached the end of its life.

If the battery is in good condition and fully charged, the next culprit is typically corrosion. Inspect the battery terminals and your cables for any signs of corrosion or other debris that may affect the connectivity.

The final solution is a damaged fuse or frayed wire. Any issues in the electrical system can prevent your starter, alternator or other electrical devices from working properly. These issues are more complex and difficult to determine, so you may need an expert mechanic to inspect your vehicle.

How To Replace Your Worn Car Battery

Batteries usually need to be replaced every five years. If it’s time to update your auto or powersports batteries, follow these steps for safe and efficient replacement.
