Battery ODYSSEY or OEM Audi

Odyssey makes the best. Optima for a middle end battery.

If willing to pay for a Optima yellow top, I suggest you get an Odyssey battery instead. It's a much better battery for about the same price.

I finally spent the money on an odyssey extreme on my 7.3 along with an aftermarket starter and battery cables. Absolute game changer in the wintertime. I could leave it out in the cold for a week and it would start faster than the old battery setup would in the summer.

I’ve ran odyssey in my RZRs and they always held up through abuse and neglect.

Buy an odyssey. It will pay itself off in the long run nor let you down. I just ordered one for my Rubicon.

I'm running a 320 amp alternator with AGM odyssey battery so far no issues

Yes, 2009 Audi TT, $800 as part of my yearly service in LA. Complained to Service advisor about the labor, and he took 20% off the battery portion.

Based on these comments, I definitely replaced my battery last year wrong. I just ripped out the old one and slapped in the new one. I didn\u2019t code anything haha

It is a great car to drive.\n\nThe battery range is very, very poor. On a cold day the range may be in the 120 range. It is exp naive to maintain as most parts on it are coded which means Audi dealer only

Odyssey and wasn't a fan died quick
