When I was working, and parking my vehicles in a hot, non cooled garage, I would average 2 Summers on most any battery. Regardless of brand or type. Now my garage is evaporator cooled, and I keep all my vehicles on smart battery maintainers, and I'm getting as long as 4 Summers. Also, I'm driving a lot less since I retired as well.
I also have fans in front of the grilles, that I run on a timer, for a good half an hour when I get back, That, along with the evap cooling really gets rid of under the hood heat.... Doing whatever you can to dissipate heat will serve longevity much better than battery type, size, or length of warranty.
