HI I had my alternator/ Battery replaced about 2 months ago now it seems everytime I dont start the car for 2-3 days its completely dead. I have exchanged the battery twice now thinking maybe I was having bad luck with them. Also I dont have any aftermarket alarms, sterio equipment ect. I never had a problem at all before the alternator went out. Does anyone have any ideas of what could be drawing power out of the battery?
Thanks in advance for your help!!!!

 

You got a defective alternator. It doesn't charge your battery enough, thats why the battery dies.
Go to the mechanic who replaced your alternator and tell him to check it ; it should make 14.1 V even with headlights and defroster on.
