LOL - the tech doesn't know how that system works, obviously.
30 minutes isn't going to do squat to the AGM batteries. I charged for a couple of hours to get to 75% when mine were still at 40 some percent.
The sensor doesn't charge.

It doesn't take days - in fact, it can be ready to go in a day.
So if you start it and take it home, let it sit 2 to 4 hours, and start it again, it may be ready to go.

If that tech was up on things - he'd have read this in his training - (see my post above showing this same thing)

I'm finding other sources that say 5 days. Is this for older Jeep?

"4/2020 Intelligent Battery Sensor (IBS) - Operation (Battery Control Module) - ALLDATA Repair https://my.alldata.com/repair/#/rep...ype/392/nonstandard/1491386/selfRefLink/false 1/2 2014 Jeep Truck Cherokee 2WD L4-2.4L Vehicle > Starting and Charging > Battery > Battery Control Module > Description and Operation > Components INTELLIGENT BATTERY SENSOR (IBS) - When IBS is disconnected from the battery, the device loses its stored memory. When power is restored, the IBS starts a relearn process. Until the relearn process is complete, accurate battery state information is unavailable to other vehicle systems. The IBS relearn process requires five normal, operator initiated starts with at least eight hours of engine off time between each start. Usually, the process takes a few days of vehicle operation to complete. Remember, the relearn process is restarted every time power is reconnected to the IBS. This has a major effect on the stop/start feature."

Here is what I have recorded for the week:


10/24 - car in for service, stop/start not working

IBS replaced on 10/25 - car in shop until 10/27 for other work

I picked up car on 10/27, Stop/Start did not work on the way home - display charging volts = 14.2

Driveway testing on morning of 10/28 – 54°

display volts w/switch on acc – 12.1

batteries in parallel measures with multimeter – 12.24

main battery measured with multimeter – 12.26

aux battery measured with multimeter – 12.32

display voltage when cranked – 14.5

batteries in parallel measured with meter when cranked – 14.57

I think you got that one right. I returned to the dealer this morning. They worked a little and then went for a test drive. The stop/start still wasn't working. They worked some more and after 4 hours they returned my Jeep. All systems were working. I left in a hurry but later called the service manager to find out what they did. the service manager said that they had to charge the batteries through the IBS sensor. :) At least it was all warranty work. Only thing is that the skelton crew they work on Saturday did NOT include somebody to bring in doughnuts.

I ordered the odyssey 94r online. With the new battery, my auto stop start works again. Ours probably been over a year since it last worked. Haha

Anyways, i did not have to return my battery for a core fee.

The factory battery sits at 12.4. Is it worth putting that 50lb paperweight inside one of those solar charged portable battery boxes?

If you have a use for the battery box, I would try it. Worst case, you end up buying a better battery for the box. I replaced just the main battery, and everything is working as it should now. I didn't have to return the old battery, so I'm looking for a way to use it. It's not well enough to run the truck, but it's not dead yet.

Back to the dealer for the 3rd time. Stop/Start and Remote Start not working. The first 2 times, my Jeep was OK for one day. I let them have the Jeep for a week while I was on a trip. They changed the main battery. Seems to be OK now. Glad to be spending warranty money.

This was a fun spool of information.
I read through all 19 pages, however didn’t read anything conclusive.

Seems as if the remedy is to replace both batteries? Or to run with a tender??

For hooking up a tender or charging while batteries are still in the jeep- has anyone snapped a few photos… I want to ensure I understand visually how not to blind charge.


For replacement options- looks like the couple that were successful with warranty and the dealers just had new factory batteries put in. I’m considering odyssey’s… any cons?

I hear there are issues with the diesels and the genesis dual battery setup?? Anyone have a link to more information?


for data- I have a build date 2/22 JTRD and for the past couple weeks regularly see 12-12.2 v on the dash every morning ….Start stop doesn’t seem to have any issues after oil/coolant is at temp. Voltage jumps to 14v when running around after starting

The remedy depends on your situation and issues. Voltage drop in the cold is normal. At barely a year old, you should not be having battery problems, but that is affected by environment, driving habits, and the quality of the original batteries.

When charging, or using a battery maintainer, connect to the nuts on the top of the terminals that the cables connect to, not directly to the battery posts or terminal nuts. One connection to the top of the main battery will charge both batteries.

I have not looked at the diesel version of the Genesis kit. What I have read is that it is not well implemented. The problem is there is just not room under the hood for a dual battery system like the gas version.

If the original batteries fail during the 3/36 warranty, they are covered and will be replaced. I was hoping for free batteries, but mine outlasted the warranty by about three months. Replacing the batteries outside warranty just depends on how much you are willing to spend. On my gas Overland, I put in a ACDelco 94R that I got from Amazon. Better quality (hopefully) and higher CCA rating than the original. I paid $159 for it in September.
