You’re buying everything in pictures. Both drills work, one is a 9.6v and the other is a 18v. Only one battery for the 9.6v drill and 4 for the 18v drill. The three batteries that I have a multimeter on show voltage but will not work on the drill, may be fixed but not sure. The batteries on the drills are good and take a charge as well. The charger will work for both types of batteries that’s with set. See all photos!
