How long is a car battery good for?

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, flaky stuff around my 500SL’s battery post?

The white, crusty stuff that can accumulate around 500SL car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

How do I remove corrosion from my 500SL 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 500SL 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.
