Why is there white, crusty buildup on 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?

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 C2500 owner’s manual for instructions on how to do so.
