Battery OEM Honda or OEM BMW

2016 328i. Original battery still alive and kicking!

The battery on my previous F20 lasted over 12 years before I replaced it last winter. Had enough voltage but bad resistance readings, mechanic advised me to change it for the winter.

I’m just over 10-years on my ‘15 M235i.

I got 12 years out of the original battery on my E90.

My e93 Battery Laster from 08 and I replaced it this year due to it started having Problems. It still kinda worked but I didnt want to have Problems. Still 17-18 years on a battery is bonkers

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 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.

I also just had a new battery installed by BMW, $600 for the honor.

Dealer measured my 2021 m340xi battery at 700cca last week under load test (vs 850 cca capacity) and said battery needed to be replaced. Terminal was stamped 26th week of 2020.

I replaced the battery on my wives 2009 honda accord. Started her up and it made this awful sound the second the AC kicked on. Bogged down the engine and made it run rough. It has never had AC issues until now and I'm sure it's coincidence with the battery changeout.
