Battery OEM Mazda or OEM Volkswagen

Still running on its original battery that came with the car.

My 2014 jetta TDI does the exact same thing as in your video when the battery is dying. I've had the car now for 6 years and it's happened 3 times. If the alternator checks out fine, then I would attempt a new battery.

Change it when it can no longer meat a battery test to spec, which has good margin before it starts causing issues, like freaked out ECU or hard starting.

OEM VW Battery lasted 7/8 years, despite me nuking it by foolishly leaving my lights on. Sad day.

I replaced the battery of my 18 SE this year and did not code the battery. I replaced it with an OEM one from VW’s parts department and had no issues

OEM battery died at 3 years old / 50,000km. Was tested and deemed defective and replaced for free. Replacement OEM battery is currently 3 years / 45,000km old and I'm a bit nervous on long trips this winter lol. I got it tested last month out of paranoia and it came back all good.

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.
