Battery OEM Hyundai or OEM Audi

Can confirm, worked at a battery store for a few years throughout college. Audis for some reason always lasted much longer than any other car brand.

My S4 battery is going on 6 years and it pops off like a brand new battery in Minnesota weather.

Original battery in my GF’s Elantra finally died today after 10 years.

I had to replace my comfort battery as well 2 weeks ago. The please start engine warning came on all the time before cranking. I ended up getting the batterie from an Audi dealer since the local VW dealer didn't have one in stock. At Audi the battery actually cost $ 60.00 less than if you would buy it from VW.

Replace battery with OEM battery AFS still in operable on and off.

I went to an official dealership and they told me the battery is faulty, and replacing it would cost around 185 euro, labor included. I checked online and it seemed like in the Netherlands a comparable battery costs between 85 and 120 euro.
