Johnson Controls makes 99% of the automotive batteries in the USA. I know they make the Mopar batteries too.
My truck is a 2002 and I still have the factory batteries in it, and they do get worked hard in the winter time in Alaska. The truck is parked outside and not always plugged in. I did just buy a Battery Minder to recondition them and see how long I can keep them going.

My '02 is still original equipment. A little maintenance goes a long way.You my friend are one very charmed individual to get that kind of life out of an oem battery
My 03 still has the OEM's also, still show green in the little round windows, and tested "good" with my little handheld loadbank.
