Non-AGM Battery - 2020 Gladiator

[ShadowsPapa]

Quit dawdling and get that lead acid battery swapped out for the correct AGM. Might as well get a fresh AUX battery also to re-baseline everything if being prudent.

What he said - and charge both batteries fully before installing them, leaving the IBS disconnected while you do so. That will reset it, it will re-learn and things will be fine at least in the battery area.

(this is the IBS - intelligent battery sensor - in case there was a question)

From FCA (Jeep) -

Battery Exchange
IBS DOES NOT NEED TO BE REPLACED WITH NEW OR RECHARGED BATTERIES. However, it
might require SOC adaptation.
IBS SOC Adaptation (Learning)
Learning needs 1 crank and 2-4 hours of quiescent/sleep time.
Quiescent/Sleep time is defined as Quiescent phase: [-500mA, 50mA] battery current

Yeah - I know. Will be doing this soon for sure.

So.....simply purchasing two (2) new AGM correct batteries for the vehicle won't be sufficient??? I have to also charge them additionally and perform the re-learn process for it all to work correctly?

Over or under engineered?

What he is stating is not that hard to overcome. Since the batteries are in parallel, you want both starting out at their maximum capacity rather than one possible having sat on the shelf and having a low state of charge and the IBS is fighting to levelize them to bring them back up. They are already mismatched capacities and it is best to give them the a best chance out the gate of being fully charged before being put in.

I am a proponent of switching to one battery. The quote above covers some of the logic involved in the switch. A Walmart Everstart Premium AGM group 94 battery will have as much cold cranking amps (CCA) as both Mopar batteries combined. It also comes with a 4-year warranty and the warranty can be exercised at any Walmart.

This photo is a couple of years old so the price might be different:

This is the factory group 94 battery. You get this bigger battery if you have an option package that includes auxiliary switches.

This is the factory auxiliary battery.

Since the dawn of batteries in cars, you should always charge batteries before installing. That's been a given since I started in the trade long ago. Charge each battery, install each battery.
While you are doing that, you have the IBS off the main battery anyway - unplug the small wire connector and set it aside. Just letting it sit does the relearn.
Then - simply put it together and let it sit - it will take a couple of drives but it will learn without you doing anything more.

So really, you aren't doing anything more than you should do with any car other than you have two batteries, and the IBS to unplug and leave sitting while charging the batteries.

Sounds like more than it really is.

No matter what you do, or what you own - you should always charge new batteries before installation, but it's even more important with two.

I've had several Jeeps with this system, and haven't had any problems other than the fact Jeep batteries often don't last very long. it's really not all that scary in the end.
