Battery OEM Volkswagen or OEM Mercedes

Starts fine even in -4F weather. Will probably swap it this year with another OE battery as oddly i have better luck with OE batteries and they tend to be cheaper than Autozone/Orielys/Advanced.

2017 got a new battery in 2023 before winter, didn't have a no start issue but figured it was time. Went with a dealer battery, was only $138ish for the 72ah upgrade and replaced it in their parking lot to get the core charge back.

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.

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.

2022 ID.4 in Canada. Have had two replaced. Luckily when it happened it was in my driveway for all three times. Hooked up a charger to the 12v for a few hours and it started like nothing was wrong.

The battery VW uses in the ID.4 is trash. I had it replaced under warranty in my 2021 after about 2 years when my car died in the garage and I had to get assistance. The tow truck driver got it going with a jump starter. It\u2019s now just out of warranty in year 4 and I get the \u201cLow 12V\u201d warning on cold days.
