How often should I replace my car battery?

Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.

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

How do I clean a corroded Wrangler battery terminal?

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.
