Thanks as well, very easy to do other than that loan 10mm bolt is a challenge to get back in to start

Is this the same for a 2008 s63? I see a bigger battery in the trunk.

[@accessgastroclinic8919]

? does this apply to the CL63 2010 model year?

[@shushuwu]

Is the battery on a 2014 CL 550 in the same place? If you could, I could really use the help😅

[@overlandersnorthwest]

How long do they last?

[@silver750iL]

IMPORTANT NOTE Later stop/start cars can have the main battery under hood/bonnet but have a bigger aux battery behind the back seat backrest. They do not have this small battery. Mine was a 2011 S350 bluetec diesel
