Currently have a MB EQS that’s fantastic for about 1/3 of what it cost new.
The battery in my MB was the original Bosch so 20 years old when I replaced it.
(for general reference Lion are one of the worst battery brands out there. Exide are OK but that's far too expensive. Bosch and Varta are generally the exact same product with different stickers on and are always good, and rarely all that expensive.
I have a 2020 GLB250 and mine was saying "12V battery" on and off for a few weeks. I checked under the hood with a multimeter and my main battery did have a low voltage while the car was off. I replaced it a few weeks back. No more notification.
I had the same issue on my w213 - same warning every now and then until one day it just didn’t start. Replaced the battery and solved the issue.
m.b. buy a Benz battery?
If the battery dropped to 9V it is probably defective.
In the 166 body MB ML/GL, its under the passenger seat, with barely enough room to reach the rear terminal. It's also so far forward that you can barely grab the fuckin thing. Oh, did I mention that it is a group 49 battery.
I went to a Škoda dealer to look at a car to buy. The car was a Rapid 1.4 SE DSG which was advertised at £8995. The car was stored remotely from the dealer, basically in a field. The battery was completely flat.
A few hours later he came back with a new S4 018 Bosch battery (original one was Yuasa HSB056). He assured me it had the same specs, despite being a different brand (40Ah, 12V). He installed it, and then told me it was a “slightly different base size” from the old one.
