The truck seems to have some parasitic drain it is a 2018 battery and it's probably sat a year. Although whenever I change the battery with those side terminals and air box in the way if I don't get a solid connection and it clicks a couple times that will put it in security mode also.Define "long periods".
My Monte Carlo gets parked from November to April, or thereabouts. I expect the battery to be powerful enough to not have trouble after being dormant for 4--5--6 months.
