The battery in your Chevrolet supplies and stores energy. Whether it’s starting your car engine, running your air conditioner, or listening to music with the car off, your battery powers it all.

You’ll want to keep your car healthy to make sure you can use your battery exactly the way you like. Read below for answers to common questions about car battery health from the Martin Chevy service team, and learn about a few warning signs that indicate a drained or faulty battery.

Common Car Battery Q & As

My battery warning light came on. Should I be worried?

This light actually means that your car charging system is not working correctly. Though it does not directly indicate a battery problem, it does mean you are at risk of being unable to use all your car’s systems.

This warning light tells you that your alternator is not generating enough energy to start your car and also recharge your battery, so get it checked out right away to ensure your car keeps running and starting smoothly.

When does a car battery need to be changed?

The three most common causes are:

1. User error, such as leaving your lights on.
2. A parasitic drain that keeps using your battery even after you turn your car or systems off.
3. A bad charging system.

How can I tell when my car battery might be dying?

Here are some signals that may indicate it’s time to get a new battery:

• Engine is slow to start
• Other electrical components (e.g. windows, windshield wipers, etc.) do not function properly
• Illuminated dashboard battery warning light
• It’s been a few years since you last had the battery changed

Are car battery chargers good?

Car battery charges can be good in a pinch, but if you find yourself using one often, it’s probably a better idea to shop for a replacement battery from Martin Chevy’s OEM parts catalogue.
