Battery ODYSSEY or OEM Volvo

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

I had a 2004 Volvo s60 with a battery that lasted 15 years before I changed it. The mechanics were impressed. Really helped that it was located in the trunk.

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.

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.

Only things that went a couple months back was the EGR and a window mechanism. And the battery a year before.

I have a friend who bght volvo XC-90. He had horrible experience with the battery in just couple of weeks and had to replace it as part of warranty.

Odyssey and wasn't a fan died quick
