Storage: disconnect battery?
I have to leave my 2016 GL63 for four months and have no ability to plug in a maintainer. I do not believe there is a standby mode in the 2016, so I'm considering simply disconnecting the battery and reconnecting it when I return.
I also considered keeping a second battery in the rear area jumped to the main battery for double the AH - but I doubt even that's enough to last the four months and would rather not ruin the battery.
Any advice? Ok to disconnect for 4 months? Should I disconnect the aux as well? Will I face major hassles when I put it back in service?
Many thanks!

I have a three-car garage which opens into a large common parking area. The three-car garage will be filled with my wife's ML, and my GTS and SL63 - all of which I will have on maintainers. However, the low man on the totem pole (the GL63) will be out in the common parking garage which does not allow us to plug anything in to the outlets. So my only way to plug it in would be to rent out a spot somewhere that has power (which would be more hassle, I think, than the other ideas discussed here.

Good thought though - thank you!

Have you considered a solar charger? You should be able to find one that outputs enough current during daylight hours to keep your battery maintained. There are many from which to choose.

I'd thought of that, but don't have a good outdoor spot to park the SUV. Since it is in an underground garage, I am afraid a solar option would not be viable.

Four months of sitting should be fine if the garage is not freezing and the battery should be fine. Even if the main battery gets a bit weak, jump the car to start it and all will be fine. Because disconnecting the main battery for four months will kill the backup battery and reset all sorts of car functions that will need to be reprogrammed.
