Battery OEM Audi or OEM Volvo

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.

I got 14 years out of the battery in my Volvo.

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.
