Why is there white, crusty buildup on my Seville’s battery post?

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

How do I remove corrosion from my Seville car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Seville owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
