Why won't my E550 battery stay charged?

A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you may have a habit of leaving your car doors open and the lights on overnight.

How often should I replace my car battery?

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.

What is the white, crusty substance accumulating on my E550’s battery post?

If you notice white, crusty stuff around the battery terminals of your E550, 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 E550’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my E550 car battery?

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.
