Starter, Solenoid and Cold Temperatures

I was away for a couple of months and I had my 2002 Explorer 4.0L parked in the driveway at home. When I returned home at the beginning of December, it wouldn't start and my 10 month old battery was dead and frozen. The auto store replaced the battery and I plunked the new battery in the SUV and it started immediately no problem. Suspecting a parasitic battery drain (cab light), I removed the battery and keep it in the house fully charged and warm just in case. The terminals and wiring are good and a tune up was done last summer.

After a week and after a cold snap (-30 C), I needed to move the SUV. I plunked in the battery; it would click but wouldn't start. I gave up on it until it warmed up recently to -14 C. I plunked in the battery, tapped the solenoid, put it in neutral; turned the ignition key about ten times until it cranked. It started no problem. I ran it for about an hour and took it for a short drive. It ran beautifully.

The following day which was about -22 C, I tried to start it and no luck. It appears that the starter or solenoid is affected by the temperature. Since I have always parked it outside, is there a way to warm up the starter/solenoid or could it be another problem?
 






Can you put a battery tender on it? I keep one on my Lincoln and it keeps the battery charged. If I don't put it on, after a couple weeks it's too low to start the car.

Harbour Freight sells them; so does Sears. They really make a difference, especially in the cold.
