Battery OEM Chevrolet or OEM Mercedes

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

When I bought my used bolt from Carvana. I had scheduled a full review at the local Chevy service center/dealership. They confirmed the battery had been recently replaced, other than that perfect condition.

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.

Chevy Volt. It was a true gateway drug to the world of EVs and showed me that I can do most of my driving solely on battery so I didn't need to worry about range anxiety.

I drove a first gen Chevy Volt before I bought my 2022 MYP. I actually loved the Volt but it didn't have much range. The Chevy Volt had about 37 miles of range and my round trip to work and back was 34 miles. I drove that car on all electric 95% of the time.

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.

same issue with daily driver 2021 E63. In this case though, the car doesnt give me a warning as much as the Mercedes app on my phone - it alerts to low battery -even critically low, but when I get into the car it starts and there is no message.

Just bought a new G63, same issue!

I’ve had it 3.5 years and it just started doing the “Stop Vehicle Leave Engine Running” thing about a month ago.
