E450 battery charging
Is there a procedure poster, somewhere, that outlines the procedure to hook up a battery charger to a 2024 E450? I ask because I plan on storing my 450 for the winter, as it's far too nice a car to drive on road salt encrusted roads, and it's something that I've done with other cars, in the past. However, with today's "electronics laden" cars, it's not always a good idea to let the battery run down, so I like to put a charger on the car every 5-6 weeks, during the winter.
Obviously, I don't want to do it incorrectly, and mess something up......

I have a 220D in the Uk and needed to charge my 12v battery and noted that it’s an AMG type battery so your charger needs to support that charging type. Hope this helps you can see this on the label on the battery in the boot/Trunk

I would use a trickle charger that will keep the battery fully charged, and does not need to be disconnected until you are ready to use the car again. I have not used mine on my W214, but use it for my W238 (2019 E450 Coupe), which tends to sit for extended periods of time.

I have a Battery Tender (brand name) that I keep attached to my GL450 as I don’t drive it often. I just hardwired the supplied pigtail to the jump start terminal under the hood and plug/unplug the cord to the pigtail as needed.

I'm reluctant to use a tender, as my garage, where the cars are parked, is attached to my home, and in case of the tender developing an issue, I don't want to burn the house down. I've been using Optima AGM batteries in my Corvette, for a number of years, so I have an Optima charger, which is designed for that type of battery. I'm just looking for some advice as to A) where the battery is located (trunk or engine compartment), and (B) whether there are any special hook-up steps that need to be followed. For instance, in our former Jaguars, you hooked the positive cable from the charger to the (+) post of the battery, and the negative cable from the charger to a ground post of the car's chassis, adjacent to the battery.

Did they change the location of the 12V battery for the W214? I think the 12V battery is located in the engine compartment for the W213.

For W214 models, it's in the trunk. The 48V is in the engine compartment under the hood.
