The new Makita 12 volt 3/8" drill is about half the weight and less than
2/3'rds the size of the DeWalt 12 volt 3/8" drill.

Behind the DeWalt on the left is the 12 volt Ni-Cad battery for that
drill. In the middle is the 7.2 volt Ni-Cad battery for our DeWalt
screwdriver. On the right is the 12 volt li ion battery for the new
Makita. It is by far the smallest of the three batteries.

Is that the printer you bought at Wal*Mart?
