It’s Thor’s turn to get a new battery soon. I’m seeing the “do not use aux switches battery charging” message briefly flicker when starting. And at last oil change recently, when they checked things, the battery was starting to look low. I knew it was coming. My question is- for this 392 engine, are these common batteries that most Jeep dealers would carry? Or are they special order kind of things?
 
Are y’all changing the auxiliary battery also? It’s a pain to get to otherwise.
 
As far as I'm aware, there's no aux battery on the 392. Is that not the case?
I think you are correct, I assumed it did but looking like it doesn’t from a quick search. Thanks. That thing was a pain to get too
 
OK, here's a sad update. So this morning I thought I'd take it to my local dealer to get the battery swapped under warranty. Went to start it, and click click nothing. Battery was acting very dead. AAA came out and jumped it, but my poor Jeep didn't make it out of the driveway the battery was so dead. Therefore, had to get it towed to the dealer on a flatbed. (AAA came back out with a flatbed and earned their money today. If you don't have AAA well worth it. The visits and tow today cost me nothing. And they were quick.) So my Jeep is currently at the dealer, I'm awaiting the call to come get her. Something a little concerning though, may be normal but- When the Jeep was jump started, engine was running but the engine light was on and shifting was very clunky. P to D, clunk. D to P, clunk. I assume it's because the battery was almost gone. I hope. I told the service tech to make sure the transmission is OK. It didn't make those noises until the battery died, could be just that, but still... and everything should be covered under warranty.

Moral of the story- when you get routine maintenance, have whoever you deal with check the battery level. Always have this done. Keep a close eye on it. I've had my Jeep only 7 months, and it turned into a 5,000 pound paperweight overnight due to a low battery. This is what you do not want to happen to you- (what a way to start a Monday. Screw Mondays!)

Sorry for all your troubles. Do you know your Jeep warranty includes roadside assistance and towing if needed?

Yes, thank you, but I knew my local AAA towing service is located just about 3 miles away from me, so I knew it wouldn't take them long to arrive. I have no idea where Chrysler service comes from and I didn't want to wait all day. And they probably won't replace the battery on-site. If you want the battery replaced, for free, the Jeep dealer has to test the battery for a couple hours and determine if it's officially too far gone. In my case it was of course. So all this towing and battery replacement cost me nothing. Zero.
A final note is that a lot of battery data bases haven't been updated to reflect the new Jeep 392 model. I called some local garages, when I was considering having it replaced at my home, and they couldn't find the battery in their system due to the 392 Jeep being so new. Maybe like others have mentioned Batteries Plus is the place to go if you want to pay for your battery replacement.
 
After your initial post I did some searching and found the three places I looked did not have the 392 in their database. I do believe it is a 94A battery. There are only a dozen or so different batteries in the main stream auto business.
 
About 3 weeks ago my 392 wouldn't start. They replaced the battery and said it was defective and had a bad cell. a week ago it wouldn't start again. Finally jumped it off and took it to the dealer. They kept it a few days and said there was a significant draw on the battery. They say it was the radio so they held on to it for a few days and replaced the radio. I just got it back today and all seems good. Not sure if they really fixed the issue or if they are just guessing. Jeep is only 6 months old.

You had a 392 towed for a dead battery?

I thought most 392 guys were wrench turning HP junkies. Guess not.

10, 12, and 13mm socket or wrenches I cant recall which 2, remember neg off first and on last
 
Batteries are under warranty for 3/36 due to the Aux battery abortion move. My 392 just did the same thing he described with the aux buttons

Mine has been doing that for a year. So I will call to see if I can get a new battery sent to me.
 
Has then group 94R been confirmed. Just no way a stealer is gonna warranty my battery, by the time I drive 1 hour to the stealership the battery will be fully charged and be fine. Can’t leave it overnight. They won’t warranty the battery if I just pull up with a loose battery for them to test. And I would rather drop hot things on my face then talk to them about anything. I will leave my battery in till it won’t start the Jeep and pay for replacement. So I need to confirm what battery I need.
