More generally, if the car is dead when you find it, hook up the charger with a minimum of disturbance (e.g. don't go fiddling with the light switches, etc.), then look to see what'* active now that juice has returned: lights, level-control pump, power antenna, etc. If the Twilight Sentinel relay has stuck closed, it'll probably still be stuck closed after the battery dies.
If in doubt, just turn it off for a few days to eliminate it as a suspect, then see if the problem remains.
If the battery has gone so far dead that it'* reversed polarity (which can be checked out of the car with a DC voltmeter), it'* truly toast. If it'* only gone dead once or twice, it might be salvageable.
