Abstract

An adapter for a power tool battery. The adapter enables a battery having a first configuration, such as a “slide-on” configuration, to be used with a power tool and/or to be charged by a battery charger having a second configuration, such as a “tower” configuration. The adapter may also enable a battery having one general configuration, such as a “slide-on” configuration or a “tower” configuration, and a first connecting structure to be used with a power tool and/or to be charged by a battery charger having the same general configuration, such as the “slide-on” configuration or the “tower” configuration, respectively, and a second connecting structure different than the first connecting structure.

8. The combination as set forth in claim 7, wherein the insertion portion is insertable into the opening along an opening axis to support the battery on the adapter, and wherein the adapter support portion connects to the tool support portion along an adapter attachment axis, the opening axis being generally parallel with the adapter attachment axis.

9. The combination as set forth in claim 7 and further comprising a locking assembly for locking the battery to the adapter, the locking assembly including

a locking member movable between a locked position, in which the battery is locked to the adapter, and an unlocked position, and

an actuating member operable to move the locking member between the locked position and the unlocked position.

10. The combination as set forth in claim 7 and further comprising a locking assembly for locking the adapter to the tool housing, the locking assembly including

a locking member movable between a locked position, in which the adapter is locked to the tool housing, and an unlocked position, and

an actuating member operable to move the locking member between the locked position and the unlocked position.

11. The combination as set forth in claim 7, wherein the battery includes a battery terminal assembly, wherein the power tool further includes a tool terminal assembly electrically connected to the motor, and wherein the adapter includes an adapter electrical assembly including

a first adapter terminal assembly electrically connectable to the battery terminal assembly, and

a second adapter terminal assembly electrically connectable to the tool terminal assembly to electrically connect the battery to the motor to selectively transfer power between the battery and the motor.

12. The combination as set forth in claim 11, wherein the battery terminal assembly is supported on the insertion portion of the battery, and wherein the first adapter terminal assembly is supported in the opening defined by the adapter housing.

13. An electrical combination comprising:
