Ow. That's embarrassing.
A better question is: "Why does Nest require a battery to operate?" Every furnace and A/C system I've seen provides DC voltage to power thermostats. Why can't the Nest thermostat run off of that and only use the battery to maintain configuration during a power outage (or even better, use flash memory for storing configuration)?
