How to Remove a Battery From a Mercedes

1. Allow your engine to cool for a half-hour before beginning any work under the hood.
2. Open the hood of your Mercedes by pulling the hood release tab inside the vehicle. Locate the battery. If necessary, refer to your owner’s manual.
3. Using a combination wrench, loosen the nuts connecting the battery to the negative cable. The negative cable is black. Remove the cable from the battery.
4. Loosen the nuts connecting the cable to the positive cable, which is red. Gently lift the battery out of the vehicle. Be careful, as the battery weighs about 30 pounds. Dispose of the battery per your local regulations.
