Abstract: An impact wrench is provided with a battery to power the motor. The impact wrench provides improved portability since the impact wrench does not need to be connected to an electrical extension cord or a pneumatic hose. The output drive, motor, batteries and main handle may be aligned along the axial direction of the tool. The batteries may be located between the motor and the main handle.

Abstract: A power tool is provided. The tool has a housing containing an internal drive system that drives an output member that engages a workpiece and exerts mechanical force thereupon. A force sensor and a positional sensor are operatively connected to the drive system to sense characteristic variables of the drive system during engagement of the workpiece. A light unit is positioned on a front end and a top portion of the housing so as to be able to direct light of various colors onto the workpiece. A control unit is operatively connected to the drive system and the light unit so as to control the light unit based on the characteristic variables of the drive system measured by the sensors. The light unit may illuminate a colored light on the workpiece depending on whether or not the workpiece was determined to be fastened according to predetermined specifications.

Abstract: In at least one illustrative embodiment, a cordless power tool battery may comprise a housing, a power storage unit, a first release button, and a second release button. The housing may have a first side wall and a second side wall spaced apart from the first side wall. The first release button may be coupled to the housing and extend along more than half of the first side wall of the housing. The second release button may be coupled to the housing and extend along more than half the second side wall of the housing.
