You should have about 14.4 volts across the battery with the engine running, check it with a mutimeter.

If your battery drops from 12.7 to 12.2 volts after standing 2 hours with all the fuses pulled you have a dead battery unless there is a power leakage that pulling the fuses does not affect. Try disconnecting the earth after stopping the car, if the voltage drops the same your battery is definitely knack3red.
