Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.

How do I clean a corroded E400 battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your E400’s electrical system running smoothly.
