You don't turn off the battery when the generators are on in reality. The plane is still drawing energy from the battery, just the generators are charging the battery. So the BAT switch should ALWAYS be on when the airplane is on. This way if the generators or engines fail, you still have electrical power. Proper way to shut down the King Air 350 engines (from what I have seen real world pilots do).
Make sure the autofeather and prop sync switches are off. Once you are done with ATC, turn off the avionics. Pull the engines back to full idle with the prop at full and the mixture at Low Idle. Let the engines stabilize at their absolute minimums for 30seconds or so, then turn both generators off. Unlock the gearboxes then immediately and quickly pull the mixture levels back to cutoff and the props back fully into the Feather region. Once you have confirmed the engines are winding down, turn off the battery and whatever else you need to, then exit the airplane.
That's what I have seen pilots in the real King Air 350 do. It may vary slightly for other King Airs. Do note however for jet pilots the procedure is different.
