Battery ODYSSEY or OEM Audi

Commenting here for others to find. 5TA915105B has dimensions that align with Group 48/H6 specs. I bought an Odyssey 48-720 and it was a perfect fit. Bonus tip - FCP Euro has it for $250 and it includes their lifetime warranty.

I’ve had a group 34 Odyssey in my ‘04 TJ for 4.5 years, no problems at all.

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.

Being designed for industry they have a reputation for much longer life (up to 10 years) and better performance at cold temperatures.

Odyssey batteries have served me well. AGM. My Benz has the battery under the passenger seat so I it’s irritating to change. My last Odyssey lasted 9 years and didn’t fail: I just decided to change it as a matter of maintenance.

I'm on my second Odyssey Extreme (first one lasted from 2017-2022) and they are pretty good. I got the 34R-PC1500T. I give it a charge once every month or two with the Odyssey charger.

Sounds about right for a dealership, just had my battery replaced at a euro shop and it was 448 total

I've had decent luck with Odyssey batteries

I installed the old battery after recharging it and it has been working great until now. The new battery was faulty and I ended up returning it for a refund.

I've had a few of the Odyssey batteries... Never lasted more than about 14-18 months before dead. Take a look at these: https://shop.antigravitybatteries.com/products/starter-batteries/automotive/ag-h6-rs/
