X166 aux battery
Where is this sucker located? I see some videos showing in the right rear panel, others show in front of the main battery (I Hope not, that is a PIA to access).
This is a 2015 GL350
Thanks to anyone who can help.

2013 GL550
Yes the video Saud posted on youtube saved me too. I have a 2013 GL550 I just replaced the main battery and used this video to find the aux battery since it was not under the passenger seat by the main as I expected. I replaced the OEM auxiliary with a Duracell 12V 1.3ah battery. it is slightly smaller but the rubber bumpers in the housing keep the battery snug. I replaced my OEM main battery with an AGM battery as well.
