Abstract: A power tool system that includes a power tool having a receptacle for receiving a battery pack, the receptacle including a mechanical interface for mating with a battery pack, a first battery pack having a battery pack housing, the first battery pack housing including a mechanical interface for mating with the power tool, the first battery pack housing having a first width dimension in a direction generally perpendicular to a direction in which the first battery pack mates with the power tool and a second battery pack having a battery pack housing, the second battery pack housing including a mechanical interface for mating with the power tool, the second battery pack housing having a second width dimension in a direction generally perpendicular to a direction in which the second battery pack mates with the power tool, wherein the second width dimension being at least about 1.5 times the first width dimension.

Abstract: A battery terminal having a pair of contact tulips that mate with a device terminal in a mating direction. The first of the pair of contact tulips mates with the device terminal in a first contact plane and the second of the pair of contact tulips mates with the device terminal in a second contact plane. The first contact plane is generally parallel to the contact plane. Both the first and the second contact planes are generally perpendicular to the mating direction. The resistance between the first tulip and the device terminal is approximately half the resistance between the second tulip and the device terminal.

Abstract: The present disclosure is directed to a cordless reciprocating saw including a mechanical interface for attaching a removable battery pack. The mechanical interface includes a strike plate to reduce the effects of vibrational forces on the battery pack.

Abstract: The present invention includes a battery pack for a cordless power tool including a plastic housing including a mechanical interface for mechanically coupling the battery pack to a corresponding mechanical interface of a cordless power tool. The mechanical interface includes a rail, a groove and a sliding surface. The battery pack also includes a bracket encased within the plastic housing wherein the bracket includes a first portion positioned within the rail of the mechanical interface.

Abstract: A battery pack is provided for use with a power tool. The battery pack includes a housing and a plurality of battery cells connected in series within the housing, such that an inter-cell node is defined between each pair of adjacent battery cells. A plurality of terminals is at least partially exposed outside of the housing for coupling the battery cells to at least one of a power tool or a battery charger. The plurality of terminals include a positive terminal, a negative terminal and one or more inter-cell terminals, where at least one of the inter-cell terminals is electrically coupled via a positive temperature coefficient thermistor to one of the inter-cell nodes.
