Why is there white, flaky stuff around my XJS’s battery post?

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

What do I do about corrosion on my XJS 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 XJS owner's manual to learn how to disconnect the battery cables.
