Does an alternator generate AC or DC?

The output of an alternator is direct current (DC). When the alternator pulley is rotated, alternating current (AC) passes through a magnetic field and an electrical current is generated. This is then converted to DC via the rectifier.

At what speed does the alternator charge the battery?

For battery charging to occur, the alternator’s voltage must exceed the battery’s voltage. Alternator may not generate sufficient charging voltage until alternator speed is greater than about 2000 RPM.
