Help. Time sensitive! Calling Jeep Gladiator Battery Experts. Need help and I'm in Peru.

Much easier would have been to bypass the AUX battery and charge / replace the main, but it is what it is.

Sure, NOW you come up with that...........

I thought the same thing but put off mentioning it when he stated his mechanical skills were pretty low. I think it would run the risk of him blowing the fuse array trying to walk him through a aux battery bypass and then he would be in a pickle.

That's my fear anyway - he's going to have to be careful to not let the wrong cables touch the wrong places. Last thing he needs is a blown high current fuse.

Even I am at point considering buying a fuse array to keep on hand as a spare if needed.

I had thought of that......... stuff happens. We've even seen things blow over a silly loose connection.
Let Benny know.

Problem is - you need to match a "reset IBS" to a fully charged battery. It's going to assume it's that way.
Yeah, you can do whatever you want, but............ will it work properly and have the best battery life, the charging system operating as it should? Or, will it get by?

IBS won't be reset unless it's disconnected for long enough - some people pull cables off, swap out battery, put IBS back on and it was never disconnected for long enough.
I can easily swap out the crank battery - and not reset the IBS.

QUOTE from FCA STAR document -

it be should installed onto a fully charged battery and follow the same learn procedure above.

Man they make these things complicated. I recently did this on an ‘18 compass which thankfully sat fully disconnected for over 24 hrs so I assume it reset but ?‍

I love modern tech…but also really enjoy the simplicity of older tech ?

Eric if you’re still reading this I just wanted to tell you that I appreciate your YouTube adventures. You’re keeping it real and I appreciate that.
Safe travels!!

I dunno, sometimes the more things change, the more they stay the same.

Didn't he say in his second post that he removed the main battery and disconnected the aux battery?
That takes more mechanical aptitude and unskilled courage than removing a ground cable, taping it up, and pulling a fuse out, and it would still be a better travel fix.

Here’s some issues to consider:

• If both batteries are dead, replacing the main with a dead aux still connected in parallel is not a good idea.
• If AGM batteries are hard to come buy replacing the main with a traditional lead acid with an AGM aux still connected is also a problem. The AUX is an AGM. Batteries of different sizes connected in parallel isn’t great. Of different chemistry or design is worse. There’s enough difference with AGM that it effects how they are handled by chargers/tenders.
• The truck only needs the AUX for ESS but it’s effectively always connected.

Regardless of what people think about ESS, the AUX battery and all the controversy you need the truck running reliably. I’ve spent some time in Ecuador and Peru. Neither are good places to be stranded. I’ll be surprised if you find good matching batteries outside of a major city.

I would do the following:

1. Disconnect the ground from the Aux. I have the diesel so getting to the Aux is a bit different. On the gasoline engine people say you can go in through the fender rather than the engine bay. If that necessitates removing the fenders or potentially breaking the fender clips, I wouldn’t do it. instead go through the engine bay. Removing the fenders, not the fender liners, frequently results in broken clips. Maybe someone here can detail getting to the Aux battery in the gas engine.
2. Pull fuse 42.
3. Disable ESS whenever you start the truck with the dash button
4. Find a new main battery. The charging system is designed for AGM for what that’s worth, but a conventional lead acid will be okay under the circumstances. As others have stated it’s a 94R or H7. You can measure the existing battery and find one that simply fits and can be secured.
5. Worry about the final resolution of ESS, the Aux, and a new AGM starting battery when it’s more convenient.
6. Consider finding a plug-in tender of some kind.

Not sure if they would be more likely to have the exact parts on the shelf? I might even ask about warranty though you maybe over on miles now, but "electrical" could be covered and honestly just sitting for 2 months should not 'ruin' your batteries though I can see how it would but Jeeps sit at dealerships for extended periods too.

Reading your build sheet, your picked up in May 2021, so 3 years, 36k miles, just not sure if you exceeded that mileage yet. Worth asking about...

Eric,

Hope you figured out your battery situation. One reason I will continue to buy Jeep are the communities like this forum: there are some pretty smart people out there that know exactly what to do and how to do it.

Also, heat doesn't sound bad - it's about to be 12 degrees in Colorado this weekend...

So simply pulling the cable resets the IBS..
How long is Long time?
30 min. ?
Additionally I replaced the small battery and Big one was still good . I dont remember waiting for IBS to reset.. Didnt know this I think I did disconnect negative on big one and then started rest of the job (went through fender. ) I never new it even had a IBS ..lol ..If I forgot can I still just pull that off and reset again?? I drive lots of miles. I am sure I am getting to the end of the main batteries life surely I am. As the 17th of Dec was 3 yrs. When I get to sites I will set there with ACC position on the switch and listen to radio without truck running to save full and oil life etc.. I don't know how that guy got in there and pulled that aux out without taking out those push pins. I am sirta big and old and just couldnt do it so pulled the bottom 4 push pins. Worst thing was. I couldn't get then to grab even had them try and put them on . So went to their body shop and got clips and screws worked like a charm.

Minus 5 for highs starting Sunday with lows even lower. Shock to system after near record warm December!

Just FYI according to the patreon post yesterday he found batteries in town, not sure if he installed yet but that one hurdle was overcome.
