Battery Replacement on Mercedes C-Class W203

Model: Mercedes Classe C W203 - Years 2000-2007
Part: Battery

To access the battery, as shown in the video, you may need to remove the air filter. Once done, disconnect the two terminals by loosening them with a 10 mm wrench (always remember to disconnect the negative terminal first). Isolate both terminals with masking tape and remove the two 13 mm bolts that secure the battery to the lower bracket. At this point, you can extract the battery. Proceed in reverse for reassembly by placing the battery back in position, tightening the securing bolts, and reconnecting the two terminals. Check the proper functioning of the new battery.
