Ironraven,
It could be your starter solenoid but that's remote - last on my list for the symptoms you describe.

My first thought is the battery. Even though you charged it and it tried to start before "clicking", I'd say bad battery ...or charging connections... or you didn;t charge it long enough. As you know, the cold weather is the silent killer in your case.

If you can, take it out and bring it into warmer climes to charge it. Let it get its full charge.... a good charger will also de-sulfinate it. Then try it. Also as you know, it could very well be that, even though you might charge it and get it good to go, it may not last much longer.... and certainly, it won;t go through many more stone-dead revivals.

Good luck
