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

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

What do I do about corrosion on my Reliant 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.
