Battery OEM Mazda or OEM BMW

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.

Bmw e91 318d del 2009, cambiata la batteria originale quest' anno.

low miles 10 yr old vehicle means its possible it has the original BMW factory installed battery. Some of those can last 10 years, I had a 2013 bmw 3 series and in 2022, I finally changed the original battery.

BMW i3… loved that little toaster but 80 mile range wasn’t cutting it anymore. I still enjoyed running errands and zipping through parking lots.

My cx30’s 2023 battery died as I was coming to a stop sign. As I was rolling to the stop sign my breaks failed hit the car Infront of me and the could not get my car to start.

Mazda OEM batteries known for underpowered and short shelf life. If you are in any kind of extreme climate for more than one season, there's a likely chance of failure.

162km at 42% battery is still kinda poor for 2025.

My 2025 CX-30 battery is already showing signs of dying but I bought the car in April but then had surgery in June and only went back to work today so it sat for long periods and I do leave my dash cam in parking mode. It might come back some after being driven more or it might not.
