Battery OEM BMW or OEM Mercedes

Changed my battery this year on my 2005 e46 coupe. There wasn’t a date for the old one, but 3 codes and for one (H1B582092) ChatGPT said that it’s 2005 battery, which just sounds insane if true.

I still have oem in my 3 series from 2015 !

I replaced mine last month after 143k 2013 f30

I still have the original BMW battery on my 2005 e46 sedan

my n55 project car is original from 2011, still haven’t changed it. shows zero signs of weakness

BMWs are super good on batteries. They seem to last 9 years or more even in the midwest with extreme cold.

I got a full ten years on mine. 2012 F30 320d that i've had from new, now got 85k miles.

I had 8 years on original battery on 2017 750i. I replaced it. It was barely holding 12V. Few functions were not working like stop/start and such.

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.
