What does it mean when the battery light begins to glow on the dash of your Mercedes? Oddly enough, your battery is usually not the problem. It's your Mercedes alternator. The Mercedes alternator acts like a little generator under the hood, charging your battery and providing power to your electrical accessories. When your Mercedes alternator begins to fail, the battery has to make up the difference, and that's where the battery light on the dash comes in to play.
