Consensus:

After talking to some members here, and hearing straight from the horse's mouth (ModularTurbo), this mini battery doesn't have much reserve time and has a history of not starting in below zero weather--so unless, as Cbrrmike said, you have a battery tender hooked up to it all winter, expect it to be dead. If this was purely a race car, then I'd jump on this. Unfortunately, that's not the case.

Thanks, everyone, for the help.
