Well, you must be right. Let it run for about 10-15 minutes and shut it off. Went back out to start it again and it's dead. Guess I'm buying another battery today......fml.
you don't have a charger? might take a while to charge if it was ded dead

Nope, just the wife's jeep with the new battery from a few weeks ago.
you can take your battery to pretty much any auto parts store and they can charge it and test it, just leave it with them for a couple 2-3 hours, then you'll know for sure

Alright, do you have a charger you would recommend I get?

Paracitic draw of some flavor. CAN bus, alarm, phone charger left plugged in, could be anything.
On my S10- i had to go to the mechanic three different times before he found all of them. The last time I actually found out the biggest draw was the ‘you left your key in the ignition’ switch inside the ignition cylinder was super worn out and at random times throughout the night it would just start going ‘DING DING DING DING’ for hours on end- and I only found out after i got home one afternoon, and had the door open, key in hand, headlights off, and it was still chiming. If your battery is in good shape- you have draws somewhere.

I'll take it to AutoZone or advance and see what they say.
I'll look into charger/jumpers to keep on hand either way.
I made sure I unplugged everything besides the stock radio so I should be ok in that retrospect.

anything really I like the old school shumacher's, I bet if you poked around on offer up you could pick one up pretty reasonable, I wouldn't worry about there being any new issue's cropped up, it's just that time of year and it sat for several days the alarm alone could kill it if it was already weak.

The wife and I were talking about it and we think the last time the battery was replaced was in late 2015 early 2016 so it makes sense for it being on its last leg.

Dual battery conversion? Mine is getting pretty old and I’m thinking about getting two AGMs

I have dual batteries in both of mine. They are interstate batteries and I wires them in parallel. I drive my 6.2 more than my 6.0, but they both fire up very quickly, even after sitting for over a week. It's just good insurance having dual batteries.

@CHOO CHOO do you have anything plugged into the OBD port, like a Bluetooth scan tool adapter?

As much as I'd like to, I don't think I will. Not sure why you would need two batteries unless you have other accessories or just want reassurance. Then that means I have two to replace every 4-5 years.
Obd port is empty unless I plug the autocal into it.

I have a set of those exact same MSD wires that a buddy of mine gave me off his Camero about 5 years ago that I never put on my 5.3. They seemed a bit long for it. I wonder if they'll fit the 6.2l better.

One good battery is all a guy needs unless you’re running a lot of bass imo. You should just get yours checked out like others have said, and 10-15 minutes of idling isn’t going to charge it for shit.
Dropping her off tonight for state and emmisions inspection tonight. 
you have to drop it off? how long does that take and what do they charge?Dropping her off tonight for state and emmisions inspection tonight.
