I just checked the FreezeAlarm at my place on Long Island. Temperature was normal (set way back), and power was on. However, the battery was notably below usual full 9.3 volts (8 point something), not in an emergency condition, but low enough that I suspect power may have gone out for a couple of hours at some point. That would have been long enough to weaken the battery, but not long enough for the cold air to drop the inside below the 40 F setpoint I have it at.
