Why won’t my Suburban battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the lights on overnight. Stop in for a free battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.

What is the average lifespan of a car battery?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

Why is there white, flaky stuff around my Suburban’s battery post?

If you notice white, crusty stuff around the battery terminals of your Suburban, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your Suburban’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my Suburban vehicle battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
