Battery Exide 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

IMHO, Exide works well till the last second and then dies off without any symptoms. Amaron shows alot of symptoms like extra cranking and lights dim for interior and dash lights when it's nearing its demise. Hence I moved to amaron. So should you.

After reading all replies and knowing the price of the dealers option, I took my chance with a Exide battery AGM 12-23, it was a perfect fit.

I don't think they are good at inverters, but I have used their battery for ups which lasted 4 years, now i am using the second one which completed one year

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.

Battery died July 2022. So got 3 years out of it. New battery is AGM (OEM VW from dealer). Stock battery was not AGM.

My Bullet needs Amiron, not happy with Exide. It's some design tuning, I suppose

My cousin has a 2018 Atlas and a month ago he called me and said he car wouldn't start. It'd just rapidly click. So I drove over there and gave him a jump. Still wouldn't start. So I thought maybe it's the starter motor. Called a bunch of repair shops and they said the battery is dead and needs to be replaced.
