The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

What is the white, crusty stuff around my Wrangler’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 Wrangler 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 clean corrosion off my Wrangler vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your Wrangler’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
