12 volt battery?

I know this has been discussed in other posts but I’ll ask again. My family and I are going to Greece and eventually Albania. Flying out this Wednesday.
If my car is charged to 85%, will it take care of my 12 volt battery? We will be gone for 3 weeks.
Thanks in advance for any assistance in order for me not to have 12 volt battery anxiety.

A $30 1 amp battery maintainer is a small expense and inconvenience to keep your battery charged while you're gone.

You do need to make sure you have the latest update though.

It will absolutely take care of the 12V battery, and will only use about 2% of the main battery. It would be even marginally better for the heath of the main battery to leave it at 50% before going away for 3-4 weeks.

I left my car for four months at 45% and the 12v battery was fine when I got back.

No Mercedes yet
You'll have no problems at all. I have left my EQS (SUV) parked for several months; the 12V battery gets recharged periodically, and my main battery lost only a handful of % of charge.

As others have stated, you will be fine leaving the car as it is without a trickle charger. My car is stored in Florida for the summer with no charger and occasionally the 12 v battery reports as partially charged, but within 24 hrs it reports as charged, the way the car is designed. For June and July my main battery went down 4%. As long as the main SOC is between 40 and 70% you should have no problems.
