What is the white, crusty stuff around my C2500’s battery post?

If you notice white, crusty stuff around the battery terminals of your C2500, 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 C2500’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my C2500 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.
