I wouldn't take the battery out of the car. Leave it in there and put the maintainer on it. Like I said, I've been storing my car this way for 7 years in temps down to -40 and I'm still on the same battery.
FauxDiablo does make a good point about the coolant. Test it and make sure it is good to -40. If not replace it or adjust the mixture accordingly. I would not store the car with the coolant system drained - that is another bad idea.
