Jafo 21 that was very nice of you to try to find that for NorseWagon. I believe I sent that to him awhile ago and got a "close but no cigar" response lol. Personally, I like the one you (we) found just as well.
Thanks guys: Yes, I did see the above poster, but I like the other one better. Just picky I guess.
Different subject: I keel getting warning messages from my 2019 Wagon that start battery is low. (Voltage)
Could be as I only drive it once a week, but still not normal. When bought this car last year from a BMW dealer (Prior Trade-in)
They told me new tires and a new battery.
Took it for drive today, it started right up, but as soon as I was back the voltage dropped again.
An hour later I measured it at just below 12 volt. Charging now at 10 amp/hour.
Question: What is the standard battery with these cars: Old fashioned Lead Acid, or AGM?
A quick google check told me they cost $99 and up to $235. (The MB dealer with probably charge a bit more than that.)
Either the battery is old and needs replacement, OR I have a "ghost load" slowly draining the battery when the wagon is parked.
Seems pretty much normal for these cars the battery drain if not driven like everyday. Best thing is once a week put it on a battery maintainer over night and that will solve your issue plus prolong the life of the agm battery which are around 300 dollars now give or take.
I think Merc 2012 AMG's advice is on the money. While our situations are different (I have two batteries, a 12 volt and a 48 volt starter battery), if I don't drive it for a few days, my app tells me the starter battery is "partially" charged. Usually, a 30 minute spin gets me back to "charged". But the consensus on the hybrid forums is that I need to keep the car on a battery tender if the car's not going to be driven for any length of time. Unlike even 10 years ago, those batteries have a lot work to do other than just providing a burst of starting amps. There's a lot of electronics to run also.
Ok, thanks guys.
Well, so this is almost normal then?
Got a small problem: My battery charger are old school, no setting for AGM or Gel, only lead acid.
(They take a charge at different rates)
As a charter boat captain I have dealt with 12 volt systems and 12 volt batteries for over 30 years,
but on boats we have 4 ways of charging the batteries: Alternator, Generator, solar panel or shore power.
I am a bit disappointed that my late model Mercedes with a recent battery can't maintain a healthy charge for a week or two.
My 20 year old boat keeps 100% charge for 2 weeks, in a dark boat house with no sun to energize the solar panels.
(I turn the battery switches off before storing the boat. Can't do that on a modern car, every little chip and gizmo need some
micro volts to retain memory I guess. Wish we had that for humans: Plug me in Scotty.)
At any rate, thanks for heads up, I will look for a trickle charger for a single AGM battery.
All good.
Answering my own question here:
Found a trickle charger on Amazon for $29.95: 1 AMP only, but in
24 hours, that should be 24 AMP/Hours, if the Wagon needs more than that, she is sick...
First impression is good, heavy connectors, strong clips, built-in fuse and best of all: The AGM option.
The 1 AMP trickle charger worked great, 13.0 volts this morning.
Will leave the car alone and see how much the voltage goes down over the next few days.
Different subject:
B0 Service coming up, the Indy dealer quoted $489 and the MB Dealer $500.
Not much of a difference, might as well do the dealer.

Glad to hear bout the trickle charger working! Simple and inexpensive solution.
Didn't want to derail the thread, but the battery in my W113 literally exploded while hooked up to one of those, and it was still charging after the fact. Battery was old, and may have had other issues...so does not apply to your new AT...but the 'smart' charger certainly contributed to the incident. Other high-end manufacurers rebranded them, and they were extremely popular as CTEK units, so likely an anomaly...but I replaced all three I was using immediately. The resulting hazmat mess I would not wish on anyone.

Had my Wagon in to the local MB dealer yesterday for a B service.
Milage was 10,050 and they quoted me $500 and change on the phone.
When I dropped the car off the SA said this is the last Pre Paid Service.
Wow, news to me, but I took it.
Previous owner Pre Paid 3 years and 40,000 miles of service, hence my
10,050 mile car got the 40k service which was a B plus new windshield
wipers and other stuff.
Pleasant surprise and I gladly forked over $82 for tire rotation and balancing
which was recommended but not required for this service.
(All good expect they pumped up the tires to much, it rides too hard at 41 psi,
35 was just perfect before the service, but easy to let some nitrogen out.)

Traded my E300 Sedan for an E400 Wagon!
I did it – I traded my 2017 E300 in for a CPO 2018 E400 Wagon, P3, Cavansite Blue Metallic, Designo Interior.
I love it, as I knew I would. It's my 4th M-B Wagon, so I know exactly what to expect.
