This message recently began to pop up every time I start the Jeep and then goes away after a couple of seconds - is it something to be concerned about?

Most likely your battery is dying. I took mine in last weekend for the same issue. They ran a test and it was at 600 something out of 800 whatever and graded out as bad so they replaced it under warranty. Mine did it for maybe 10-14 days before I took it in. Toward then end I could hear it take a tick longer to crank so that's when I took it in.
 
An alternative answer is that your battery is simply low and needs recharging. My 392 is a dedicated trail rig and is only driven on the weekends… so I place it on a trickle charger or else I get the same message 👍🏻
 
Mine was battery. Jeep tested and said battery ok but took longer to crank and message popped up every time even when only parked for a few minutes. New battery and problem solved. I just got an agm from Walmart with 4y warranty. They are good batteries and if they fail are promptly replaced. Was $180 and I don’t have to keep fooling with the jeep dealership. They can’t replace battery unless it tests bad and the long test which they did takes 1/2 day.

"I smell what your steppin in"...do not have time for stealerships to play around...two things I absolutely dread, warranty work and insurance claims, hope I never have either again...

I agree except that I would probably go for a new battery, they have gone up quite a bit in the last 2 1/2 years.......
 
I disconnect the battery completely and recharge the battery with an agm compatible 10amp charger and then reconnect the battery and the message goes away for about 6-8 Months.
 
mine gave me a warning saying check charging system, I then went to my off road pages on my head unit and saw the voltage at 11 then it would go back up to 14 back and forth, I took it into the dealer and they said everything was good. So I read its a battery saver mode so that your battery last longer, but it scared the shish out of me.
 
Just put $1700 worth of Deep Cycle AGM's on my RV...the others lasted 5 yrs, but a few things I didn't realize even after having AGM's for years...keep it charged at all cost, do not let it sit or operate in a discharged state....if you use one insure it is fully charged after use

6 tips to extend your AGM battery's life
  1. Charge your battery regularly. It's critically important to charge your battery as often as possible. ...
  2. Use smart chargers. ...
  3. Use temperature-compensated charging. ...
  4. Use the correct float voltages. ...
  5. Use an alternator temperature sensor. ...
  6. Minimize voltage drop.
I had a discharged AGM that two other chargers would not pick up at all, this charger not only picked it up it charged it fully in 24 hrs...

On a very long road trip in the middle of nowhere NM in my GMC truck I noticed the voltage was low and assumed my alternator was out. I drove about 95 MPH for an hour or two thinking I needed to get to civilization (and my hotel room) before my battery died on a Sunday evening so at least I could find an alternator in the morning. I assumed the battery had a certain amount of time left in it rather than miles so I drove fast. I got to my hotel, googled it and found the alternator in those vehicles has something like 9 separate charging modes and mine was simply in battery preservation mode or cooling mode or whatever. This was two years ago and that alternator is still fine.
 
Well, I have an interesting situation. After much testing it seems that (a) I only have 1 battery, (b) the AMP power steps have a small parasitic draw waiting for me to open the door and (c) my 392's programming keeps it "live" for several hours before reporting back to the mother ship and then shutting down. In the meantime the steps continue the small draw. Yesterday I had it detailed after a seriously muddy day and I guess the guy had the doors open & closing a lot so when I got in this morning it wouldn't start and I had to jump start it. Service writer told me about the only thing I can do is put a battery tender on it! I need some kind of power step and I don't think Mopar makes one that works with the 392.

Maybe call AMP? There seems to be some hit and miss with power steps. I have the RSE steps and haven't had an issue but some have had an issue with a constant draw like you. I assume the differences are due to installation but idk.

The only Jeeps (or any regular production gas powered vehicle that I know of) that have two batteries are those with auto engine stop at the stop light. None of the 392 Wranglers have that feature so none of them have dual batteries.

The confusion, though might be that those vehicles with two batteries are not the same type of setup that we think of dual batteries in an off-road situation. With ESS once the engine is no longer turning it cant produce any power and the lights, blower, radio etc have to run on battery. When ESS kicks in all those accessories run off the second battery so the full cranking power of the main battery is available to start the engine the moment your foot comes off the brake.

ah that makes sense - I wasn't sure why a 392 would have a 2nd battery unless it's running all kinds of power sucking gadgets lol

yeah that's the next step is to talk to Amp. The tech said it has a lot to do with how the 392s are programmed to wait for mother ship communications and mine has an extra long wait time and nope, it can't be reprogrammed.

I got the same message. Started about two weeks ago when we had like -10 degree weather. Went to start the Jeep and it barely turned over. Now that it has warmed up, the battery seems stronger as Jeep cranks up better. However, I still get that message.

My 392 is two years old so just assumed battery is on last legs. I've read in other forums the stock battery isn't that good.

Does anyone have any recommendations on replacement batteries?

Age is probably part of my problem as well - mine was built in January 2022 and I took delivery in March 2022 so it's about 2 years old now. I look forward to seeing battery recommendations.

On another note it looks like AMP has an override switch so I'm calling them to discuss it with my problem.
