I'm not too hard on my batteries, and almost always get 7 years out of them on the nose. I kind of forgot to account for the build date of my '07 JK. I think it's a late '06'er

2007 here also. A few lazy starts and then the next morning no crank at all. Changed the battery this winter - thankfully the jeep was in the driveway.

Just a word of caution for the '07 and '08 JK's... If they're still factory, it's probably a good idea to get your batteries load tested or consider replacing soon.
Yesterday after putting gas in my JK, it failed to start. Turned the key, and the dash went black. Let off the key, and some of the lights "sort of" lit up. Tried again, and got the same results.
Tried to jump it with two different vehicles, with two different sets of cables, and could not get anything more than a weak chatter or weak click out of the starter. At one point the relays in the fuse box were chattering. Things were a mess. Could not tell if it was all battery related, or computer or starter issues too.
Had a tow truck come, and thankfully got the Jeep started with one of those booster packs. No idea why jumping it wasn't working. We were hardly even getting a mild spark upon connections - and connections were legit.
I've probably had to replace a half dozen batteries over the years, and have never had one up and fail like this without some sort of warning. I knew I was due soon, but thought things were still holding up ok. Lesson learned on my part.......

My battery shit the bed this weekend and mine is a 2012. It would not start and a jump from another vehicle didn't work but the tow truck was able to get it started.

Please don't take this the wrong way, but I'm glad to hear another person wasn't able to jumpstart their JK.
I think we went through all of the correct steps - It's pretty basic, right? Even had the jumping vehicle bring their motor up to speed. It just didn't work. It still doesn't make sense to me as to 'why' it didn't work.
I've had a new battery in for a couple of days now, and all is well.
