Does the battery sound weak on cold days, but on warmer days ~40 degrees sounds fine? If so you may need a battery with more cold cranking amps. On cold days, when you go to start it turn off all accessories, close your door so the door chime won't be going off, turn off the blower/heat and the radio and see if that works for the time being.

What cranking amps did you replace it with? What was the viscosity of the oil? What were the plugs gaped at?
