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 300SDL 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 300SDL owner's manual to learn how to disconnect the battery cables.
