Getting a low battery critical in my E450 message after car is parked just a week
when I leave my E450 for just a week I get texted a low starter battery critical messaged via the me app. Anyone else have this happen? The car seems to start up fine when I drive it after sitting for a week. Must be a very sensitive threshold I guess. I’ll mention it to the dealer. Hopefully not a bad battery. 800 miles on the car. It was produced in September so didn’t sit around a lot.

I always use trickle charger on every car if I know car will not be driven for at least a day. (I also use stabil for the last 10 years, but its a totally different subject). Some laugh, but I never get low/dead battery.

2012, FWIW, I leave my 2017 E300 parked regularly for a week or more at a time while out of town on business. Never seems to be an issue. I understand that the 450 may be materially different than the 300, but I can't imagine a week is long enough to run a battery down.

What it refers to in the message is that if the battery goes much lower the Mercedes me app won’t work. I’m thinking it’s a fairly high threshold as last time this message appeared the car started no issues turned over fast and all. Next time I leave for a week I’ll try locking the car. In the locked state more systems might shut down therefore preserving battery life. If that does not work I will go the battery maintainer route. I comment in this thread what the dealer tells me about this issue after I ask them. I have not got another message since that one two days ago and I’m getting back home tonight and be driving the car tomorrow on a 1hour trip so that should charge it back up. Anymore than two weeks idle though I’d definitely put it on the maintainer.

I put it on a 2a slow/ smart charger for 2 days before it was "charged". Now there is no issue. Give it a shot.
Putting the car in sleep mode is also helpful (lock with key 3x before leaving it for killing periods)

Thanks. That gets me motivated to break out the maintainer. Ya I’ll give that a try. Maybe it just needs a good change for the night.
