  • Why is there white, flaky stuff around my STS’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 STS 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.
  • What do I do about corrosion on my STS car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals.
