I have a 2012 Sport 2dr automatic. I can't figure out what is causing my mysterious electrical drain. It killed a 6yr old battery that was on its way out. Due to age I and winch use that it was just it's time to go.
So instead of buying a new battery I took my lightly used Optima dual purpose from my trailer winch and put it in the Jeep after charging it. Worked fine, but if the weather is nice and I ride my Harley to work for a week or 2 the Jeep is usually completely dead. I have never had this issue before and never had an issue with this battery holding a charge before either.
I have even disconnected all aftermarket electrical to eliminate that as a possible issue. Anyone have any experience with tracking electrical drains on a JK?
