Something may be shorted electrically (in an unswitched circuit apparently)
or the battery may be self discharging. I had a 3 year old battery that self
discharged to the point that I needed a charger if I parked for 30 minutes.
Replaced the battery and all was well.
I say get it charged up, disconnect the battery overnight, and see what happens.
Either that, or unhook a battery lead and connect it through a stout ammeter and
see what the car's current draw is.
Mitch.
