How to Replace the Battery in a Mercedes S-Class

Model: Mercedes Classe S W221, MK 5 - Years 2005-2013
Part: Battery

To replace the battery in a Mercedes S-Class, remove the plastic cover located at the base of the windshield on the passenger side: you will need to open the hood to detach it. Once this panel is removed, you can access the underlying device, which must be disconnected from its power cables and freed from its mounting bolts. This will allow you to insert the new battery, connecting it to the cables and securing it with the bolts, then covering everything with the appropriate panel.
