Possible to replace Auxiliary battery without disconnecting main battery first?
I'm thinking of DIY Auxiliary battery replacement for E63 AMG 2014, and is it absolutely required to disconnect the main battery first? Also do I need readjust panoramic glass roof by removing fuse and reinstalling something like that. Thanks a lot.

Pretty sure some guys on this site have done this replacement and can answer with more certainty.
I wasn't clear about your roof question.

to remove AUX battery by itself it does not say to disconnect the main battery.
Just change it out by itself.
make sure you protect REd Positive cable from grounding when off battery.

I changed my main and aux battery separately. Can be done without effecting one another..
I actually didn't have to change or reset anything after the battery changes.
