Tips for replacing main battery
I did the first replacement today on my 2017 GLE350. Not an easy job because of the weight and tight fit of the battery. I replaced with a Duracell AGM from Sam's Club.
1) I had a plastic rivet/connector at the front of the air duct to plastic shelf. You can pull both off together. Then when replacing, first remove the plastic rivet and replace the 2 items separately. It's not difficult to replace the rivet after both are in.
2) Be sure and cut the carpet as far to the front as possible. This will make it possible to lift the rear end of the battery up and pull it out. It is very heavy!! I used a 3/4" thick piece of wood about 3" wide and maybe 18" long as a lever to get the battery up so I could grab it and extract it.
Everything else is pretty straight forward.
13mm socket for the 2 nuts that hold down the clamp.
10mm socket for the battery clamp nuts.

The battery cost $199 at Sam's Club. $20 core fee. I checked Costco and they didn't have any. All other places were something like 250-300. Didn't check the battery but everything seems fine after the change. Sucker is heavy!!

I want to replace the battery in my 2018 GLE550e. Mercedes wants $363.19 for the battery and $258.88 to install it. Part of the install is plugging in their fancy computer and resetting the IBS / BMS . I'm unable to find a way to update the IBS / BMS. How are you guys doing it? I hope you're not just puting a new battery in and then thinking it's OK.
Check out this video for an explanation:
In my 2021 Ford F-150 you can do the following procedure, is there something similar for Mercedes?
Costco has the H8 AGM Battery for $169.95 and I can install it myself. Just don't want to do it if I can't reset the battery management system and tell the car it has a new battery.

- Get in vehicle, close doors
- Turn on ignition (but don't start)
- Wait for battery light to come up
- Flash brights 5 times
- Press and release brake 3 times
- Battery symbol on dashboard should flash after 5-10 seconds

What they are selling you is lot of BS.
When MB batteries are good, they used to have only 2 years warranty, so compare it to 3 or more years the $200 battery from Sam's or Costco will give you.
$258 for 15-20 minutes of work? I take it gladly.
Nothing needed to be reset. and GLE remembers even garage codes after battery disconnect.

Here is a good instructional video for changing the battery in any late MB car

1 - Steering wheel adjustments for the ESP module
2 - Windows
3 - Pano roof sync
4 - Any other explicit message in the cluster
In the past, a few MB generations ago, you had to maintain the car powered when replacing the main battery. Never had to do that with either the E or ML cars. I do disconnect the battery whenever I am playing with electrics near the airbag, or ECU, and the only I recall doing once was the windows and the pano roof sync for 2008 E350. Not even the steering wheel adjustment the YouTuber did.
I do not think you will be able to find something that may not exist. The modules themselves exist, but the need to reset them sounds OFF to me

My point with the video was that there is nothing to do. The typical known issues are highlighted in the video:
1 - Steering wheel adjustments for the ESP module
2 - Windows
3 - Pano roof sync

My 2014 E and 2016 GLE remember everything when battery is disconnected.

What exact year is your vehicle, and what type of battery are we talking about here? AGM or Lithium?
I am aware of the BMS, and what it does. However, the requirement of additional human input sounds like poor engineering design and a step backward just to save a built-in resistance measuring device.

2018 GLE550e. We're talking about the 12V H8 AGM Battery located under the passenger seat. If you replace that battery, you need to plug the car into the MB computer and tell the car a new battery has been installed to update the charging profile for the new battery. This is now the new normal for almost all vehicles being made, not just MB.
Summary: a bunch of manual steps from the Workshop MB manual (WIS) listed in English, and not summarized by a YouTuber. Nothing to do with the BMS.

Check @chassis previous post, his signature. Since that thread is long here is the direct link to his battery replacement ( https://mbworld.org/forums/gle-class...ml#post8536914)

It could be though I disconnected both the main under-passenger seat and the small one in the back (near the RearSam) on the 2015 ML two weeks ago w/o any issues after that. Done the same on the 2014 E several times while cleaning grounds, soldering RearSam, cleaning Prefuse Box, and NO issues. However, I should note that I always recheck with Xentry if I triggered any code after, deleting if any (do not recall at the moment).

I started changing the font color, and it is now visible in light mode and dark mode. I will keep working on it the next day or two.

MB changes the ideas quite often, but last was that the small aux battery is for emergency gear shifting, when car dies and you need to roll it for towing.
