Does the DCF900B come with a battery?

No. It is a bare tool: the box includes only the impact wrench. You need a DEWALT 20V MAX battery and charger, sold separately.

How much torque does it make?

DEWALT rates it at 1,030 ft-lbs of fastening torque and 1,400 ft-lbs of breakaway torque.

It is a mode that limits overtightening and helps prevent fastener run-off, useful on lug nuts and smaller bolts.

Yes. Its breakaway torque handles most passenger-car and light-truck lug nuts, and the control mode helps avoid overtightening.

The DCF900 is the newer high-torque model with more torque and Precision Wrench Control. It is also larger and heavier than compact impact wrenches.

It has a 1/2-inch square drive, the common size for automotive sockets.
