Why won’t my CLS550 battery hold a charge?

A battery is in its final hour when it will no longer hold a charge. The battery might be old. Or, you may have been leaving your car doors ajar and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

What do you do with my old CLS550 battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

How much do DieHard batteries cost for your Mercedes-Benz CLS550?

What is the average lifespan of a car battery?

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, crusty buildup on my CLS550’s battery post?

The white, flaky stuff that can build up around your CLS550’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your CLS550, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

What do I do about corrosion on my CLS550 car battery?

Regularly inspecting and cleaning your battery terminals will help keep your CLS550’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.
