Well this turned into quite the project. I ended up having to hack saw the bottom edge of the battery(they have this nonessential plastic buffer around the edge probably to get dimensions closer to group 48), the Amazon battery dimensions were incorrect.
Also it's a tight fit in the trunk, but it fits, car is alive again.

The oem battery was $411.28 including tax at the dealer
The Diehard cost me $175.63 after the $30 Amazon discount.
So for $235.65 savings and a project, it was worth it to me Also next battery change will be much easier.

All other things aside, people that don't drive will replace their batteries less often than people that do. I can never get more than 3 or 4 years out of a battery. I know other guys that do **** for miles and never replace the battery before they dump the car/truck it was in! Friend of mine just traded in his 04 Tacoma not long ago and it still had the original battery in it, but that truck had crap for miles on it. Was used every day almost but his commute is about a 1/4 mile. Truck spent more time idling than driving! (because of his remote start).

ETA: I agree that, if you live in hell on earth, time will just kill the damned things. Friends I have down south never get more than 3-4 yrs regardless of habits, the heat just beats the **** out of them.

More likely the water in the battery evaporates faster in the high heat. I check the battery liquid level & top off with distilled water. I usually get 4 years life out of my batteries except for the J.C. Penny battery that came in my 1st car, it lasted me 6 years.
