Battery OEM Hyundai or ODYSSEY

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

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.

I've had decent luck with Odyssey batteries

I remember buying a brand new Hyundai in 2016 and the car only turned on once. Then I called them and they said they installed a bad battery and changed it lol. It went on to only last 5 years.

My I6 battery died after 4mo and 2200km (1370mi). Car is sitting at the dealership awaiting warranty decision.
