Why won’t my SLK300 battery hold a charge?

How long do car batteries last?

You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.

What is the white, crusty stuff around my SLK300’s battery post?

If you notice white, crusty stuff around the battery terminals of your SLK300, 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 SLK300’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my SLK300 vehicle 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 SLK300 owner’s manual for instructions on how to do so.
