Dons were leading through Warren O’Hora’s overhead kick early in the second-half, but squandered plenty of chances to put the game to bed before Carl Johnston’s equaliser with 18 minutes to go appeared to share the spoils.
But Batty’s wonderful strike, picking out the top corner from 18 yards, ensured the win for Scott Brown’s side, leaving Dons to drop to 23rd in League One.
