If this is true, in a few years owners of these cars will be in for a big shock (pun intended) when their battery dies. No this isn't for a hybrid system but the regular 12 volt starter battery. https://www.bmwpartsdirect.com/oem-parts/bmw-vehicle-battery-61218047221
Newer BMW M3 batteries cost $1900?

It's a Lithium battery.
Think it'll be a while before one needs replaced. The 3rd or 4th owner will probably just opt for an AGM.

The diagram makes it look like a 40R battery that you can get at the parts store for much less 
Nevertheless, even if it isn't 40R, some standard size battery will probably fit.

Maybe, but can the car properly charge an AGM?
It's probably got a chip in it that the ECU reads. No chip.......No charge. Kinda like those batteries that have to "registered".
If it can't be coded to out of the box I'm sure there is a workaround. Most likely the module that handles battery management has provisions for every car it's installed in.
My Touareg is coded for Cayenne shift programming. Same concept. Took 5 minutes.

When you take the purchase price of a newer M3 in perspective, the battery cost is perfectly acceptable.
Especially when you consider the cost of most maintenance on these cars
Now if you told me that's the cost of a battery on a late model Honda Civic, well then yes, that would be worth noting.
But as it stands, this is nothing worth getting excited over.

This post exemplifies why auto manufacturers can get away with charging these kind of ridiculously insane prices for common items. That have absolutely nothing to do with the cost of the vehicle itself.When you take the purchase price of a newer M3 in perspective, the battery cost is perfectly acceptable.

Here is an exact fit, OEM equivalent replacement battery for a 2018 M3 from Autozone..... Over 86% LESS.

I don't see a single Lithium battery there.
So what? If you feel it's a must have, even Lithium batteries can be had for half of what BMW charges.
So what? You said:
Those are neither exact fit or OEM equivalent.
Prove it!
I didn’t realize an AGM charged differently?
They do sell AGM batteries for cars that didn’t come with them from the factory too.
Lithium definitely charges differently from AGM....
You're like a few women I know. They don't know what the hell they want either. They just want to argue.
Wrong generation of car.
The current M3/4 use a Lithium battery. Have replaced a couple because our lot guys forget to put the solar powered maintainers on cars.
Here ya' go, $660.00 to $950.00. Take your pick.
