Thanks @Rhinebeck01, but I wouldn't recommend searching all ESS related posts on anyone.Thank @Jebiruph and do search out all his ESS related posts...
Thanks largely to Jerry, I am up to speed somewhat on this stuff...
....but evenJerry and I have found we learn more each day.. there is a lot to it so to speak..
Thanks to Jerry, I have my Dual Battery Monitoring set-up on my JL.
.
Awesome setup @Rhinebeck01 ! Where can I purchase a monitor like yours? And what other parts would i need to complete setup?@DanW
Very little out there in regard to an Aux battery replacement..
IF I were to replace the Aux on my JL today, I would go with the DieHard Platinum AGM Battery, BCI Group Size 400, 200 CCA Part # AUX14-1 .
There are a handful of others out there but this Diehard offering seems to be the pick of the litter right now.... that's not saying much though..
No, no Odyssey or Northstar replacement for the Aux that I am aware of..
As for the life span of the stock batteries(2), it is a real crap shoot. A game that I will not play..
I considered myself very lucky to have gotten 3 yrs out of the Main battery before I opted to change it before it had issues / before it died and left me stranded somewhere (I interstate travel lots) .... so, I replaced the Main with a Northstar.
As you and many other's here know, I do not use/run with the Aux battery so my stock Aux just sits in it's cradle... sits doing nothing, acting as a backup if I were to ever need it. I do maintain it with a battery maintainer..
For those that have not seen my dual battery set-up ..... the set-up that has me running with just the Main, you can read more / see, etc. here... https://www.jlwranglerforums.com/forum/threads/ess-dual-battery-management.60034/post-1340536 .
NO, my setup, is not one of those pricey $2000+ aftermarket affairs... I am not foolish enough to go that route/spend that kind of $ with my type of vehicle usage..
Here is a pic of my set-up..

YES, I ran for over two years with just the N1-N2 fused bypass jumper in place and the Aux negative cable disconnected. Doing that ...with that, I was running with no issues... just with the Main battery.. I knew though that with this set-up (running with just the Main) I had to minimize use of the StopStart system of the JL.. Thank you @SmartStopStart.com .Particularly the battery management thread as that is targeted for improving reliability. If you do nothing else, at least install the fused bypass jumper and disconnect the aux battery negative cable before leaving civilization. That's not as fancy as @Rhinebeck01 s current setup, but he ran that way for a long time and it still eliminates the negative impact of the aux battery.
You are a Godsend, buddy! I can't tell you how much I appreciate this and all the other great help you've given in the past!
Ok, mine was a very early one, so it certainly will benefit. Plus, I can hear that turbine singing away with max air! Lol!Applies to any and all 2018 JL/JLU's.... do know that some 2018's that were assembled at the factory, very late in the production year / 2018 , may already have this PCM update.
You'd have to buy the hardware and assemble yourself...Awesome setup @Rhinebeck01 ! Where can I purchase a monitor like yours? And what other parts would i need to complete setup?
Haha, thought I was going nuts not finding a link to "Jerry's Kit". Now I finally know there is no assembled kit. Too bad. Your installation looks very clean.You'd have to buy the hardware and assemble yourself...
All the hardware is available on say amazon and it is fairly inexpensive.. About $80+- total..
Do read here for info on what you need.. https://www.jlwranglerforums.com/forum/threads/ess-dual-battery-management.60034/

My Jeep is justr over 3 years old and my experience with OEM batteries over the years has been that they last between 3 and 5 years.
My JL batteries have performed well, thankfully, with no issues. So they may actually make it to 5. And I don't use the ESS, at all, so maybe that has helped. But I'm prepared at any time for one or both to go belly up. I intend to replace the big battery with a Northstar (Batteries Plus XG2 Premium made by Northstar, but with a better warranty). Pretty sure they have a suitable replacement.
But my question is about the small battery. Is there a pure lead AGM to replace it, such as by Northstar or Odyssey? I don't want that little sucker to be the weak link. @Rhinebeck01 or others, do you know if they offer one in that small size?
I've got a Northstar (XG2) in my JK and it has performed brilliantly. MUCH better than the OEM or DuraLast Golds it has had. (Had to replace a Duralast Gold that choked out early, so not impressed) It has been especially good for extended running of accessories, lights, and for winching. I don't think I've ever probed its limits.
Meanwhile, the OEM batts in my JL soldier on. It will be interesting to see if they make it to 5 years. If they do, I may go ahead and replace them at that point as a maintenance item, figuring I got lucky.
One more thing. Since I have the FCA lifetime warranty, I want to keep the factory battery set up so as no future electrical failures can be blamed on battery mods, so unfortunately, those ideas are non starters.
