Battery OEM Mazda or OEM BMW

I just changed my 2018 F36’s battery a few months ago. They really do last a long time.

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.

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.

Incan confirm they suck… i have a 2023 mazda and i have gone through two batteries. The second one died on me this week. Both were mazda batteries

Mazdas OEM batteries are horrible. Had the one that came with the car be weak so Mazda replaced it under warranty. Not even 5 months later that new battery dies, tried jumping and it was completely dead and a jump could not start it.

My'21 CX9 battery is weak, and i can clearly tell its low on voltage after sitting without being started for a week. Never tried playing music on battery though in this car.

Basically many of the oem stock items for mazda are fine, but have notoriously short life expectancy. They have to cut corners somewhere. Battery and tires are the ones I've noticed that are good for a couple years at most before they are ran through. So yeah, I've had a mazda thay needed a new battery after 2 years, one that needed a new battery after 3 years. Just how they go.
