problems with electrical system

[NiteRider]

since its been snowing, shes been outside on the driveway, and ive been driving the jeep, but every once and a while id drive her, and somtimes she wouldnt start, like total dead battery. so i boost it let it run, and it dies when the car is running(warming up).
i tried to take back the battery to crappy tire, but they say it is ok, so its my car somehow draining the battery, while running?
can anyone make sense of my problems?

I concur with it being the alternator... If you boost it and then unhook the cables, the ingnition, heater, radio ect will drain the juice in the bttery if the alternator isnt charging constantly.

Sounds like your alternator is on its way out too.

Try not to boost the car when it is completely dead in the cold. It will blow up in your face. Don't risk it - warm it up, then boost away...
