OK Never mind. Jumped onto my laptop and found this thread:

Best AGM Batteries on the Market

I know of the most recommended: Odyssey. And I’ve personally had great success with Optima over the years, but what other brands (especially private label) AGM batteries do you recommend? I need a pair of Group 34 size AGM batteries for my dual battery setup. It seemed the Sears DieHard...

Odyssey.

 

I am a fan of Odyssey batteries. I have had great luck with them over the years.
I have had cheaper batteries fail and leave me stranded. I would rather pay more for a better battery. There are undoubtedly other good options. But I stick with Odyssey because I know they work.

 

Agree, Odyssey is one of the best. But most AGM Batteries are good.

 

if it is under 3 years old your factory warranty will cover it. may as well get a new factory battery if that is the case. If not I have to say the Battery Plus X2 power premium agm is a great battery and made by Northstar which is a highly rated battery. Nice thing about Battery plus is they are in almost every town and no question ask replacement during the warranty not pro rated.
Problem I had with Odyssey is they are not readily available which I found out when I went to replace my battery. I live in a town of 100,000 and no one actually carried one and they all said a week to order one in. the battery plus store had several of the X2 powers in stock.

I get the not available everywhere bit. But I just call or order online and it is at my house the next day.

 

That is fine if you are always at home and not on a cross country trip .

 

After researching, I replaced mine with a standard (non-AGM) battery. My factory battery lasted over 5 years without any issues, so no need to supposedly 'upgrade'. Plus, I was unable to find any definative information on the JK charging system being able to adapt to an AGM battery's charging needs.

So yesterday had a warranty battery replacement on my 2017 JKU Rubicon. They put in an AGM battery made in Germany. Are the JK charging systems ok with these? Will my standard 6 amp battery charger work or my battery tender?

Most AGM batteries are similar and much better than traditional style batteries. I've been pretty happy with the AGM battery from Autozone and their warranty/prorate on batteries is pretty good. I don't expect to get more than 3 years out of any battery living in Arizona with 115+ degree heat though.

@The compatibility question, I have been running one for a year with no issues.

 

I’ve had AGM batteries on my boat for years, 3 of them. No question I wanted AGM in the Jeep after seeing how they perform and hold up on the boat. After all the research and differing opinions I could stand, I went with the Duralast AGM from AutoZone. if you’re concerned about warranty when driving across the country on Jeep trips, AutoZone stores are all over. If I’m on the road far from home with a bad battery however, warranty is going to be the least of my concerns.

 

Odyssey and I use 2 of them. My aux battery takes a beaten. I have had a drain for a long time, to lazy to find it and the Jeep now sometimes sits for weeks on end. Many times I will go out and find the battery around 10 volts thanks to my G-Screen monitor, start battery at 12.7. Either get it out on the road for a few hours or hit it with the charger and it right back up there.

My first aux battery died at the 5 year mark. Unfortunately I had to swap both batteries due to Sears no longer selling the Odyssey branded battery, was using there 34/78.

 

I also have two odyssey batteries, in my genesis set up. The starter battery has been fine. The aux battery died after a couple of years. Either I had a parasitic drain or just let the ARB fridge go too long one too many times. From what I’ve read, AGM batteries are more sensitive than traditional wet lead plate batteries to being overly discharged. Maybe so. Thankfully I got a new one from Amazon under warranty. Lesson learned: turn off the ARB after each run, and keep the Jeep (which is not my daily driver) on a trickle charger.

 

What do people like as an OEM replacement battery?

Odyssey.
Best out there

 

I went with the Odyssey from Quadratec because everyone’s praise.

 

Sometimes a battery is just a battery. I've been known to buy a battery or two from Wal-mart and have been just fine. From what I've found the bulk of the batteries on the market are made by one or two companies, just the sticker is different. Even expensive batteries fail, so I just figure go with one that has a decent warranty and has national support in case it fails on a trip.
