Why is there white, flaky stuff around my CX-7’s battery post?

If you notice white, crusty stuff around the battery terminals of your CX-7, 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 CX-7’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my CX-7 car battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your CX-7 owner’s manual for instructions on how to do so.
