With the humidifier, each battery should get you just about 2 nights. You might get slightly less because there's an efficiency loss going from 12 to 24 volts, which the machine needs, and while not a huge loss, very cold temperatures cost battery capacity. 0 degrees F will reduce the battery capacity by about 20%.
You can get a full night on each batter, with humidifier and heated tube if you have one, with a good bit "left over". If you leave the humidifier and heated tube off, and your pressure isn't too high, you should get 2 nights on each battery.
While not an exact comparison, I get 2 nights from a 100A/H battery with a Respironics APAP running 15-20, with the humidifier on high.

Too cold to breathe?
How do other folks that are not on CPAP deal with the issue? It is no different for you with a CPAP than it would be for them.
And as to heated humidification - how do you get or store liquid water for your heated humidifier in sub zero conditions? If you get liquid water at those temps, I kind of doubt that the heated humidifier would make much headway at keeping at a "comfortable" temp or maybe even free of ice.
Same temperatures, same humidity with or without CPAP. Are you in the cold cold house during waking hours? How do you pre-heat your air then? I don't think this is an issue.
