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 SL55 AMG’s battery post?

If you notice white, crusty stuff around the battery terminals of your SL55 AMG, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your SL55 AMG’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my SL55 AMG vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your SL55 AMG’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
