Default Battery is dead.

Has anyone had this problem?
Thought my battery was dead so went and picked up a new one, car started right up. The next day the car won't start as if the battery is dead, thinking maybe I got a bad battery from the auto place, take it back they give me a new one and I install and the car starts right up. Well you guessed it the next day it won't start now what are my odds that I got two bad batteries? back to the auto place and get a third one ( the guys at the auto place said that the battery was not holding a charge so they think I got two bad batteries) I don't think so. I can jump the car but it won't keep running. Something is draining the battery after I shut off the car. The car is a 93 LS400, with factory equipment.

Anyone ever heard of this happening?
