Hey guys I have a gt55 and can't for the life of me figure out how to charge the battery. I looked in the owners manual and it only tells you how to jump the car which I know how to do but I can't find the battery to actually charge the vehicle. I got a critical battery warning because I don't drive it much. Any help would be greatly appreciated! Thanks
I want to keep my '24 GT 55 on a trickle charger (I have the MB one - the dealer gave it to me with the car!) as it is going to be extra-cold weather for the next week or so, but i don't know if my car has an AGM or Lithium battery., and the manual is absolutely no help. Anyone know how i can tell for sure? The charger has different procedures for regular lead acid batteries vs. lithium.

That is not the location of the actual battery, just the jump start location or tender/charger location for hookups. It doesn't help nor explain what or where the battery actually is.
If that is owner's manual for the GT, the owner's manual for the CLE53 is the same exact thing - and fairly useless for naming the battery type and location. I cannot find the verdict on this in any written documents supplied though MBZ.
I know (at least I think I do) that AGM tenders won't work on Li-Ion batteries if the tenders get hooked up. I'm not saying go try it, however, it shouldn't work.

Maybe call the MB dealer's part department and ask if you were to replace your battery for your GT-xx, what would it be. Surely (don't call me Shirley!) they would know.

Ok Gang, these days they make trickle chargers that work with acid, lithium etc without any need to pick a setting. Below are pics of where you hook it up to and it will keep all your batteries, even the one for the 48v system all nice and charged even in very cold weather. This is for GT’s, but the G’s are very similarly placed.
You don’t need to access the physical battery. Between new trickle chargers and Mercs onboard charging dynamics, you just hook up the leads to the pos and neg and plug in the trickle to the wall.

Personally the Battery Tender Junior is the best in my book. It is designed to charge all lead-acid, flooded or sealed maintenance free batteries, including AGM and gel cell batteries etc.
Can get them on Amazon for like 50-60 bucks.
I’ve charged all sorts of different cars with them, including my RS6 that has a 12 volt acid and a 48 volt lithium ion. I just hooked it up to the under hood points like in the above pictures and it kept the batteries charged through harsh Canadian winters.

So I had someone check the trunk and underneath ... voila a white box with the MBZ trickle. There is also cigarette input in the trunk which I was not sure would work or not to charge the battery so Ill just go the traditional post route in the engine bay.
