What is the white, crusty substance accumulating on my SLK350’s battery post?

This buildup can interfere with the electrical connection between the battery and your SLK350’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my SLK350 vehicle battery?

Regularly inspecting and cleaning your battery terminals will help keep your SLK350’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables.
