If something is draining a battery that quickly, it must be pulling a huge amount of current. Even headlights will stay on for over an 1/2 hour with a good battery. Are you sure you don't have a bad battery with an internal short?

Use a multimeter on the amp setting and check it between the negative post and the negative cable on the battery to see that the draw load it.
