Battery is finally dead. It wont start the car after a long driver. I assuming it wont charge, where it should after a long drive.

Which aftermarket battery are you guys using? What's best beside OEM? Direct fit? THANKS!

Interstate MTP-91 or Sears DieHard International are popular models that work with Audis

Mx-3GSR

I put the one for the V8 in my V6

Advance Auto PArts and Autozone have a direct replacement battery that fits like a glove and is really big (lots of Ah). I got one and it works nicely. The only problem is cost, it was like $140 or so but has 8 year warranty.

I purchased a replacement from Napa roughly three years ago. It was the same size for $105. No issues with it, but I think it only came with a three year warranty.
