Narrative:

On a flight into btl we had briefed a visual approach to runway 23R back up with the ILS. Upon arrival to btl the tower cleared us to land runway 23R; after landing and taxiing off the runway the tower cleared us to parking with him. It was at this point I realized we had landed on runway 23L. No indication of the error was given by the tower. Taxied into the ramp uneventful and shut down.both of us had a duty day over twelve hours with connecting airline flight and an hour long car ride to reach the airplane followed by a flight to btl. Fatigue was without a doubt a factor.
