Trickel charger for AMG GTS
Hi I know this subject has been discussed before, however I feel I need clarification on this. I have just spoken to my local Mercedes dealer who has said that you cant use a trickle charger for the GTS because the charger cant detect when the lithium battery is charged?? Surely this cant be true, these are the sort of car that is likely to sit in the garage throughout the winter.
Also does anybody know how long you can leave these lithium batteries without them going flat/
Thanks

If it's connected to the car I've heard it's different story.
The factory battery charger supplied with my GTS is good for lead acid and LiFePo2 batteries. Your dealer maybe referring to other chargers other than those specifically designed for the AMG GTS Lithium batteries.

I have spoken to my local Mercedes dealer who has said that the battery should not be trickle charged, in fact they went as far to say that it could harm the electrics because the charger is unable to tell if when the lithium battery is charged. They have said that it is possible to keep the battery connected to the car for up to 6 months with out it going flat. It will be interesting to see how I get on during the winter, my intention is to start the at least once a month

I would ask them why did AMG include a trickle charger in the vehicle if it would potentially damage the electrical system. Like I said in my previous post, the charger included is rated for Lithium batteries.

Mine hasn't got any a connection in the boot, my car is a UK car and is an edition 1
I wouldn't think however this would make any difference? The information I was given was from a main dealer after they had spoken to a technician that actually works on these cars! I find the whole thing confusing, but they were adamant that I shouldn't use a trickle charger, is there anyone out who has had their GT/GTS on trickle charge for a few weeks without any issues? There seems to be so much conflicting information, how difficult can it be.

I've had mine for over a year and it's been on the charger with no negative effect much of that time.

From the US 2016 AMG GTS owner's manual:
Trickle charging the on-board electrical
system battery
The battery may drain if the vehicle is left stationary
for long periods. In this case, MercedesBenz
recommends attaching the trickle charger
to the 12 V socket in the cargo compartment. A
trickle charger can be obtained from an authorized
Mercedes-Benz Center, forexample.
X Switch the ignition off.
X Open the tailgate.
X Connect the cable provided in the cargo compartment
to the trickle charger.
X Connect the trickle charger to 12 V socket:.
Consult the manufacturer's operating instructions
on how to do so.
The tailgate can be closed, even if a trickle
charger is connected. Make sure that the connector
for both the connector cables is outside
of the vehicle.
The connector can then separate if the vehicle is
moved, even if you forget to disconnect the connector
cables. This prevents damaging the
cables and the trickle charger.
A trickle charger connected to 12 V socket :
only maintains the current charge level of the
vehicle's electrical system battery. If the vehicle's
electrical system battery is discharged, it
needs to be charged with a battery charger.

I think because my car doesn't have the charging connection in the boot (uk)
and some people can leave their cars for a few months without the battery going flat (my porsche would have gone flat within 6) weeks) I am not going to get a charger, time will tell

Can I replace my AMG GTS battery with a lead acid battery as I cannot afford 2449 euros for a lithium battery. Secondly what is the separate small wire for on the negative terminal of the original battery. All help on this matter appreciated
#14
the car can sit without a charge but it is best to keep on a trickle charge. Up here in buffalo NY the car sits sometimes for 7 months.The charger prolongs the life of battery. My 2016 gts shipped with a charger ,now my 2020 gtr shipped with charger.
Must be a lithium capable one or could damage battery.
Btw I have a brand new Mercedes one in box never used for $100. If anybody needs one. Reply to mxz7000@aol.com

CTEK makes one specifically for Lithium batteries. I’d be more interested in that one because I can hook the connector on the battery at the front of the car rather than plugging in the trunk and running an extension to the back of the garage.

the MB charger is a CTek. BTW, the cables are interchangeable. Mine came with a 12v plug in and the ring terminated cables. You can hook it up front if you would like . The rear boot attachment is tool-less and a dirt free environment so we non-mechanic types can keep our hands clean and not dirty the interior.

The manual for the ‘MB’ (CTEK) charger states that you just have to push and hold a specific button to ‘tell’ the charger it is working with a Li ion battery.

Dont hold me to it.

I have the same one, it stops charging if the battery is at full charge, and its designed for Lithium batteries, works fine. I used mine when flashing the ECU Tune, and use it when I'm away for pre-longed periods of time, no issues. The MB branded one looks suspiciously similar
I have the cigarette lighter adaptor so you can just plug it into the trunk socket.

How do you know if its for a lithium battery? I have a Mercedes one my neighbor gave me from either his SL63 or ML63 and it seems to work just fine on my car.
