2012 CLS 550 Auxiliary Battery Location
i was searching the forum and found one instructions file (attached) shows that the auxiliary battery is located in the trunk, but i couldn't find it there

pic of my trunk also attached.

i came across this website
http://mb-teilekatalog.info/view_Sub...=54&subgrp=030
it shoes 3 batteries in the diagram, #10, #400, #500
parts # are A0009822108, N000000004039, A2115410001
what's the function of the each one?
I believe either we don't have it because CLS63 had a start/stop eco mode that the trunk battery is used for and our 2012/2013 model CLS550 don't have that option or its somewhere we cannot see without removing some parts.
Someone please put this investigation to rest !
