  • Why won’t my SLK320 battery hold a charge? A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop by for a free battery test at your local Firestone Complete Auto Care and learn more about your battery's charge.
  • What do you do with my old SLK320 battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  •  How long do car batteries last? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • Why is there white, flaky stuff around my SLK320’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 SLK320 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 clean a corroded SLK320 battery terminal? 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.
