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

If you notice white, crusty stuff around the battery terminals of your 500SEL, 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 500SEL’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my 500SEL car battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your 500SEL owner’s manual for instructions on how to do so.
