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.

Pros: no more notification

Cons: low voltage, on and off

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.

Cons: hard to reach

Just had to replaced my battery in my 2022 Mazda 3. I’ve always heard people say the batteries are crap in these cars. There’s no way you should be replacing a OEM battery yet. They use some crap Panasonic battery.

Cons: poor quality, short lifespan

Vehicle: Mazda 3
