  • Why is there white, flaky stuff around my SLK230’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your SLK230 car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I remove corrosion from my SLK230 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 SLK230 owner's manual to learn how to disconnect the battery cables.
