Battery OEM Audi or OEM Mercedes

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.

It's a lovely car, but very bad on the efficiency. We have a 55 and the range varies from 150 in the winter to 250 in the summer. Honestly, for the money you'll struggle to get more car, it's very comfortable, quick, and has mountains of room inside. Ours is a 2019 on 70k miles, and has had zero issues

Yes, 2009 Audi TT, $800 as part of my yearly service in LA. Complained to Service advisor about the labor, and he took 20% off the battery portion.

Based on these comments, I definitely replaced my battery last year wrong. I just ripped out the old one and slapped in the new one. I didn\u2019t code anything haha

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.

Exactly the same issue I am currently facing with a month old GLC300. No resolution yet
