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.

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?

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

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.

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.
