Aux switches / battery charging message

[Viking Jeeper]

I’ll give you a pass @Viking Jeeper since you said “gas powered vehicle”. I own 2 vehicles that have 2 batteries, they are diesel powered vehicles

I caught myself just before I hit "Post reply".

 

[Viking Jeeper]

DOH! Our diesel F350 duelly had 2 batteries!

Which is why I said "gas powered".

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?

Even if there seem to be problems with them if mine goes I'm getting it replaced under warranty.

My April 2021 build still has the original battery. When the weather gets cold I always get the message. I disconnect the battery and top off the charge and it is fine. Happens all winter, as soon as the weather warms up, no more message.

I got the ‘Aux Switches Temporarily Unavailable Battery Charging’ indicator today. Happened this morning when I first started the Jeep, then again when I went to go to lunch. The voltage per my Banks iDash, which i find is generally consistently between 13.9V and 14.1V in normal operation, was being erratic and never exceeded 13.5V. Brought it to the dealer this afternoon and they ran a quick test and found the results to be inconclusive. They said they can do a full 3 hour charge which will tell them if a cell is bad or if there is another battery issue, at which time they can replace under warranty. As their ‘diagnostic guy’ is out until
Thursday, have to wait until then for a resolution.

I went through the same garbage with my dealer. The long test said the battery was OK. Long story short got the best battery that Walmart has with a four year warranty and I no longer get the warning message. The new battery has been good for several months now with no issues.

I went through the same, started with that same message, the long test did show a bad cell on mine and replaced it under warranty.

They have one specialized battery "diagnostic guy"? Must be a long, tough training track few have tackled.

We just went through this with my wife’s 21. Dealer did the long (3 hr) test and determined battery was bad and replaced under warranty. It was the original battery and she has just over 24k miles.

 

[Earl 392]

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.......

What has not gone up ? Oh yeah wages

No shit.

Interesting, I’m at 25k miles. We’ll see what happens, I assume it’ll come back with some sort of issue given the initial test was inconclusive.

I replaced battery and aux charging message went away.

 

[Dubai_Bulldog392]

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.

Sounds like a battery issue. What voltage readings are you getting when idle?

No idea, it's been fine since they replaced it.

 

[Ted392]

Just changed my battery. OEM made it 2 years.

Went to the dealer this morning and they ran the 3 hour recharge and a few other tests. Everything came back normal. They thought some of the connections from my accessories may have been interfering with the battery sensor so they relocated the sensor for me. While I’m skeptical that was the issue, I have not seen the aux switches not available message since. We’ll see if it pops up again in the near term.

Surprise surprise the aux switches not available warning is back, now seems like the 392 is struggling a bit to turn over, especially the last two mornings after sitting for a night. I bought a 3 amp trickle charger, hopefully will keep enough juice in the battery overnight to turn over in the morning so I can drive it over to the dealer.

I have a jump starter in every vehicle. My battery in the 2006 Jeep is going out and I dont really care because I know I can get it started on my own.

Mine started messaging the same at only 2000 miles. Came on here to see if anyone else was going through this. Calling dealer today
