Abstract
Abstract A portable power tool for forming wire wrap type connections includes an electric motor, a torque transmitter and a casing for enclosing the electric motor and the torque transmitter. Removably mounted to the casing is a battery pack. The battery pack mounts both rechargeable and non-rechargeable batteries so that the battery charger may not be recharged in a physically compatible battery pack when non-rechargeable batteries are contained within the battery pack.
