Recently picked up a 'as new' GTS E1 and smiling. This is my first auto indulgence after what felt like an eternity relegated to minivans and family cars. Long, previous history of BMW M'cars, older MB's and given that my first car was a '69 Olds 442 w/ a 445, turbo 400/12-bolt, this GTS strikes just the right nostalgic combination as a bona fide German muscle car. No offense to my many 911 friends, but it's also nice not to see myself at every stop light.
A couple questions:
1. Since I technically bought the car 'used' (600 miles), it appears to be missing something in the rear of the trunk that is held in place by two velcro straps located on either side of the locking mechanism. Can't find mention of this in the manual. Any idea what I'm missing?
2. Has anyone looked into a custom, extended 'quilted leather/diamond pattern' footwell or trunk liner? I appreciate the stock interior but a little retro pizzaz might be in order beyond floor a trunk mats.
The safety triangle is a European requirement only. Us cars do not come with them. Same with my ED 1 and S550 Cab.
Thats the standard MB branded CTEK trickle charger for lead acid batteries.
This is their lithium specific charger, which is the only thing I would want to use.....
That is what came with both cars and what MB recommends. The owners manual for the charger says it is for lead acid and lithium batteries. But what do they know? Use what you wish. It is your car.
Xbox - I'm confused....which part number is the lithium-specific charger? Thanks.
As far as i know, MB dont offer a specific lithium charger. If you google the part number mentioned, it is even listed as not compatible with AMG GT/S by some vendors.
.... but what do i know ....... i thought the car only had one battery up until recently
I'm still kind of confused - I've heard conflicting information regarding whether the AMG GTS has ONE or TWO batteries. Some have said the battery under the hood is the "starter" battery... but there is a "consumer" battery somewhere in the trunk... but then I've heard some say that there is only one battery - the lithium under the hood.
Does anyone have a schematic or diagram of the GTS and could check and put this debate to bed?

OK, previously I identified myself as a 2 year ED1 owner and stated that the car has two batteries. The main battery is under the hood and is lithium. The auxiliary battery is located in the rear compartment in the left side of the hatch. It is a small 12v lead acid. Most larger Mercedes have used two batteries for several years now. When it goes bad you will get a message telling you that the aux. battery needs replacement. Why two batteries?
Mercedes vehicles equipped with a dual battery system have several different modes, depending on the status of the main systems battery. The most common mode links the two batteries together, taking the load off the main systems battery and charging both batteries. The dual battery system also has two shutdown stages as well as an emergency mode that completely switches all functions from the main battery to the auxiliary battery.
During a stage one shutdown, some of the vehicle's electronic components stop working. A stage one shutdown only disables a few of the vehicle's electronic features, such as the rear windshield defroster and heated seats. A stage two shutdown disables internal power outlets and lowers the climate control fan speed. During an emergency mode shutdown, the battery control system switches all functions to the emergency battery, and only essential electronic systems continue operating at full capacity.
The part number of the MB maintenance charger is A0009822921. It maintains both lithium and lead acid batteries. That is why MB includes this charger and not the other one referenced by someone else.
There does that help? As I have said in many previous posts, most of the posters on this forum do not own a GTS. They just like to pretend and be an argumentative pain in the ***.

Awesome, thank you for the info. So, I will return the Ctek lithium only charger I got and order the genuine MB one. Did you hard wire to the front battery, or just use the cigarette lighter in the trunk? Will the MB charger do both batteries? I don't really understand how it could "see" the front lithium battery if there is some type of isolator in place for switching?

You do use the 12V "cigarette lighter" in the trunk for trickle charge. I don't know the answer about circuitry and which (or both) batteries get charged and how. Mercedes has some really smart people designing electrical circuits. Although I respect a healthy curiosity, these fine details are things I don't worry about.

I certainly hope you're not referring to me just because I have a GT
Joking aside, CTEK don't offer a multi charger - they're either lithium, or lead acid - further, they say not to use their lead acid chargers on lithium batteries.
The MB branded item is not even their more advanced 8-stage product - its just the basic basic 4-stage. Maybe it just charges the lead acid auxiliary battery, while the car takes care of the (typically maintenance free) lithium.
Anyhow, the lithium definitely provides massive cranking current - I just love how the v8 bursts into life, compared to some of the more lethargic units I've come across.

Yes, that was exactly my point. I don't understand how the MB charger can do both lithium and agm when the Ctek can't.
I wonder if one should have a lithium only charger for the front starter battery... and the MB one for for the rear?

So I just did a bit more digging. I could find no aux. battery on the left side of the hatch - only the "spare tire" continental air compressor thingy and the first aid kit.
I've run multiple searches on multiple battery manufacturers websites (Exide, Johnson Controls, etc.)
- and all only show one battery. Interesting they all point to H5 or H6 replacements... Neither of which I could imagine fitting on the left side of the hatch.
So... I'm even more confused than ever. Do you happen to have a photo of the battery in your car?

I also do not have a battery where you do. I have done some quick digging through the WIS service manual and can't find it in the electrical schematics, I suspect it may have something to do with the Dynamic package since I don't have that or maybe the High end burmester since I do have that. Not sure, I will continue to dig for info in the manual. Those are some pretty thick B+ red cables going to the module above the battery, does that module have any numbers or description on it? If it is in your car then it is buried in the manual somewhere... Also, if I can't find anything about it, I will be at the AMG factory next Thursday and will get a straight answer from the source!

More info straight from MB USA. "Some" of the very early ED1 models (like mine) have a aux. battery that was for the transmission. This was replaced by a capacitor. My 2017 S550 still has an aux battery for the transmission. In any case I would say you only have one battery. Sorry tpo send you on a wild goose chase.

Do my 2017 S550 Cabriolet and 2016 AMG GTS have auxiliary batteries in addition...

Dear Dr. Couser,
Thank you for your email to Mercedes-Benz USA.
The 2017 S550 Cabriolet has a main battery and a auxiliary battery for the transmission.
The 2016 later build AMG GT S's only have one battery. Very few early built GTS models had an auxiliary battery for the transmission, later replaced by a capacitor.

So, probably all US ED-1's have the aux battery and can charge from the regular trickle charger, while later cars, all GT's for example, should use a specific lithium charger.
