Yep, I also live in Texas, and the longest battery I think I've ever had is a Duralast Gold that lasted me from the summer of 2011 until a few weeks ago. Otherwise, their lifetimes are usually 3-4 years at most, regardless of how fastidious you are about keeping it watered up, etc...
Heat kills batteries, and we have plenty.
