Reviews of OEM Mercedes battery

m.b. buy a Benz battery?

If the battery dropped to 9V it is probably defective.

Currently have a MB EQS that’s fantastic for about 1/3 of what it cost new.

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.

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.

Historically, OEM Mercedes batteries are really good and last many years.

Everyone's suggesting things that might save you half a percent or so, but no one has pointed out that by driving at 80mph, you lose *around 30% more battery* than if you were doing 70mph over the same distance

For my Mercedes sprinter I had the same battery in it for 10 years. I went and bought it at the dealership. Since the last one lasted 10 years. I shouldn’t have a problem with it.

I don’t have an AMG, but a 2024 CLA 200d and having battery drain problem is annoying to say the least and haven’t even had the car for a month when it all started happening. It’s been at the dealer for the past 3 days and no voltage drop there. They gave me the signal blocking key case and they upgraded the software and still can’t find the problem. Third visit in the month and new battery installed too.
