I am sure that this issue has arisen before, but I can't see to find it here on the forums.

I parked my Jeep at the airport and inadvertently flipped the switch to turn on the light bar - it was a 6 am flight and I was out of it. I returned three days later and the jeep was dead. After trying my portable starter (note to all: the charge on them should checked every three months NOT every twelve), AAA was able to give it a jump and get it started. From that moment, I have seen this icon every time I start the vehicle:

I have tried to clear it: turn it off and turn it on again, reseat the fuses, etc. Any thoughts or ideas on how I can clear the alert? There has not been any issues driving the Jeep, but better safe than sorry.

Thanks

Could the auxiliary battery be dead too and causing this?

I use a code scanner to clear mine and I think disconnecting both batteries (both cables at the main battery negative cable) works too.

Sounds like the batteries are shot, from being so deeply discharged and left like that until your return. A strong battery will also be weakened when being used as a crutch for a weak battery. If it were me, I'd replace both batteries.

For a confirmation, both batteries should be electrically disconnected from the jeep and each other. A load test will show that one or both of them are not up to snuff.

Sounds to me like a dead Aux battery - was ultimately killed after main battery dragged it down. Same light you get when you disconnect the Aux.
