I experienced the same thing before a while back with me SC400, bought a new battery and it won't crank a day later. Replaced the alternator and all was good.

Unless you know how to hook up and read an ammeter, your best bet is to take it to a qualified mechanic. Parasitic draw on most vehicles should not exceed 50 milliamps (0.05 amps).
