Battery OEM KIA or OEM Volkswagen

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

Had my '18 R since May '18 and still on original battery, 25 mile commute to work each way about 1/2 hwy . At 57,000 miles.

OEM battery in my 2016 Jetta with 215k miles is still going strong.

In Mar 2022 I went to the dealer and got a new VW battery for my GTI $151. Not knowing any better, I simply swapped it in the parking lot - I did use a OBD-II device to keep circuits alive while the battery was disconnected. All worked like it should.

My golf 2010 VW dashboard ****s down but car remains running. When it don't start take out the battery touch the two cables together with out the battery. For 15 seconds to reboot the car and it starts back.

On a Jetta, it will leave you stranded, and it being a VW, the symptoms will be nothing like a dead battery, most likely.

I'm at the third battery at 7000 miles and 6 months (2024 niro ev) and the battery is dead again this morning, like wtf.

Biggest issue was it ate batteries, never had a car go through so many batteries
