Last January 1st, I drove through all that mess from the Texas Panhandle into ABQ. After letting my truck sit in 20 degree weather, it started right up the following morning (damnit, because I would've gotten a pair of Costco H7 AGM batteries installed.
Flash forward two weeks, and I couldn't even jump start it with one truck, it took two (2016 Ram 3500 w/6.7). So, I took the plunge and had Batteries Plus order me two of their X2 Power batteries (Formerly Northstar). The CAs between the two batteries that I pulled off were not even equal to what one of them should've been putting out
Bottom line, even though it's only been six minutes months, and having driven through 110 degree Texas heat, I have no complaints. I will let y'all know when they start to fail.
