I haven't bought an aux battery. However, any AGM battery in the correct size would work. If I was going to buy an aux battery, I probably buy it at Walmart.

It is great to read all of these reports of Jeep owners who have not had battery trouble. Good for you!!! I have a 2020 Wrangler and a 2020 Gladiator. The Wrangler had battery trouble. It first presented as "stop/start not working - battery charging". I was still in warranty, so I took my Jeep to the dealer. They charged the batteries and reset the IBS. I trouble again the next week. They replaced the IBS. I had trouble again 2 days later. They replaced the main battery. Six months later I notice that battery levels were lower than they should be. I found that when the Jeep dealer replace my main battery, they installed a lead acid battery (you shouldn't connect a lead acid battery in parallel with an AGM battery). The dealer replaced both batteries (2 years ago). None of this cost me money, but I had a lot of time invested.

My Gladiator was out of warranty when I got the "stop/start not working" light. I removed the 2 Mopar batteries and installed the Premium Walmart battery. The truck functioned exactly the same with one battery as it did with two, for several months. As a Christmas present to myself, I installed stop/start eliminators in both my Jeeps.

The thing I appreciate the most about having just one battery is that I understand what the vehicle voltmeter means. In fact, my gladiator with one battery operates just like every car and truck I have had for the last 50 years. Just call me "Boomer."

How much do you want to spend ? The Odyssey OBX-AGM 27F is 930CCA, other numbers higher than an H7. The only size difference is 8.2” high, H7’s 7.5”. Not a listed fitment, but someone reported he installed them in both his JL & JT so they fit with the extra height. …… best battery thread IIRC. downside— $480
