What is the average lifespan of a 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 XJ’s battery post?

A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your XJ car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.

How do I remove corrosion from my XJ car 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.
