  • Why won't my 300SL battery stay charged? A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a complimentary battery check at your local Firestone Complete Auto Care to learn more about the state of your battery.
  • What happens to my old 300SL battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  •  How long do car batteries last? Car battery lifespan varies depending on a few factors, including driving conditions, accessories,  how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.
  • Why is there white, crusty buildup on my 300SL’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 300SL 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 300SL 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 300SL owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
