I would like to know how to change the battery in a 2008 r350 Mercedes

Try this To get to it is complicated


Move seat as far back as possible. Seat rails have covers on them - slide them forward....the left one will only slide forward, cannot be removed. Between the two seat rails you will see two little battery cover mounting nuts. Use 6 mm T-handle hex key to remove the nuts. Move seat as far forward as possible and twist rear rail covers to left and right and then pull toward rear of car. Pull back/fold floor carpet under seat from front to back (carpet is perforated so you may have to really yank the first time). There are two more battery cover mounting nuts between rear seat rails. There is a battery cover with an air vent pull it slightly to right and then lift out. There is a vent hose attached to battery on left side -- pull it out. Unfasten & remove attachment nuts on left side (low). Remove the battery attachment once those nuts are off. Push battery to the left. Disconnect battery negative lead (right) (do not let it touch pos. lead on left). Remove cover from pos (red/left) terminal and disconnect lead.
