Don't overlook a possible bad starter. That's where you might see a battery drain when the engine is off. I've repaired three different cars in which the starter was going bad and would create a parasitic load on the battery. Didn't have the boiling away problem, but eventually the battery would become weak enough from to many low discharges that the car would no longer start.
