Battery OEM BMW or OEM Volkswagen

I have seen some test results on ID3 after 100000 km and still everything is quite good on the car. Battery is not damaged like on a cellphone if that is your worry.

Same with my 2008 BMW 535d. 900ah and still going strong

I had a battery in a 93 BMW last forever like that

Regardless, while that’s sorta old for a battery, I have OEM BMW batteries going on 12 years with 89% charge capacity.

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.

Mine crapped out at 34 months. I bought a new one from VW since they had a 5-year warranty on it and it's still going...

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.

the battery in my 2016 died while JUST inside the 36k warranty. the OEM replacement lasted another 30k or so. bought an AGM replacement from Costco, but I don't expect it to last any longer.
