Where is the battery located in a Mercedes-Benz R350?

The battery of the Mercedes-Benz R350 is located under the front passenger seat, specifically beneath the co-driver's seat. To access it, you will need to remove the carpet under the seat and the protective cover above the battery. The detailed steps are as follows: 1. Before locating the battery, first move the co-driver's seat to its rearmost position and turn off all power sources and the ignition switch; 2. Next, remove the two front protective covers of the seat rails and lift the floor between the seat and the B-pillar; 3. Then, move the seat to its foremost position and similarly remove the two rear covers of the seat rails; 4. Lift the carpet under the seat to reveal the black battery protective cover, which can then be removed to access the battery.
I've been driving for decades, and the battery location of the Mercedes-Benz R350 is quite unique. It's not under the front hood but hidden beneath the floor panel in the trunk. Open the trunk, and you'll see a carpet-like cover—lift it, and the battery is right there waiting. This design is quite clever, avoiding the high temperatures in the engine bay that can shorten battery life. Maintenance is simple: regularly check the battery terminals for corrosion and clean off dust and oxidation with a soft cloth to prevent poor contact that could lead to starting issues. If the battery is aging (around 3-5 years), you might notice slower cranking sounds or flickering dashboard lights when starting the car—that's when it's time to consider a replacement. DIY replacement carries risks, so it's safer to visit a professional shop. After long-term parking, always check the voltage before starting; ensure it's around 12.6V for a worry-free drive.
