Just bumping this helpful thread to add a data point.

I just replaced the battery in my 2009 A5 after getting 11 years from the original battery. I went with the linked battery in this thread from Advance Auto. However, the batteries there are now labeled as DieHard instead of AutoCraft, so I assume they bought the brand name from Sears.

I got the DieHard Gold H9 (non-AGM) and it was a perfect match for my original battery. It had the same AH rating and was even manufactured by the same OEM in Germany (Varta). It also had a BEM code sticker on it so that I could properly code it with my VAG-COM.

I keep my cars a long time, but after getting 11 years from the original battery, I assume this one will last until I replace the car.
