There may be a flaw in the charging/regulatory system which is ending those batteries early. Lead-acid(and most batteries) do better when they remain near fully charged with the temperature constant and a light load.

Look into A123 and others. They are a big name and do large scale projects. It might be worth spending more for a warentee and peace of mind.
There are several Lithium Ion variations, some of which have excellent specs.
I have a PM going with Red about this. The manufacturer is thinking that the constant subzero exposure is a factor. To keep things to "code" in my county you use an enclosure that's vented, however it's external (but attached) to the house since my cabin doesn't have a basement.
