A battery pack is provided including a body having a first wall forming a first face from which a connection port extends for connection to a power tool or a charger, and a second wall forming a substantially planar second face. A finger notch recessed in the second face extends along an elongate axis perpendicular to a longitudinal axis of the body.

Battery pack

A method is provided for identifying a battery pack that is operably coupled to a battery charger. The method comprises: measuring voltage at a plurality of designated terminals of a first battery pack while the battery pack is coupled to the battery charger; determining how many of the designated terminals are connected to a reference voltage, such as battery positive; and identifying an attribute of the battery pack based on how many of the designated terminals are connected to the reference voltage.
