14. The power tool of claim 1, wherein the battery assembly provides electrical power to both the housing and the tool accessory.

11. The power tool of claim 11, wherein the operating portion includes a light source.

12. The power tool of claim 11, wherein the operating portion includes a vacuum.

15. A power tool comprising:

a housing including a main housing portion supporting a motor and a handle portion depending from the main housing portion, the housing also including a first tool terminal and a second tool terminal, each tool terminal electrically communicating with the other tool terminal and with the electric motor;

a battery assembly removably coupled to the housing and including a main body portion and a terminal portion, the terminal portion including a battery terminal engageable with either of the first tool terminal and the second tool terminal for electrical communication therewith to provide electrical power to the electric motor and to the other of the first tool terminal and the second tool terminal; and

an accessory attachment including an accessory terminal engageable with the other of the first tool terminal and the second tool terminal, and an operating portion, electrical power being transferred between the accessory and at least one of the battery assembly and the motor.

16. The power tool of claim 15, wherein the operating portion operates in response to electrical power provided to the accessory attachment from the battery assembly.

17. The power tool of claim 16, wherein the operating portion includes at least one of a light source, an electronic level, a vacuum, a fan, an electromagnet, a motor, a radio, and a heating element.

18. The power tool of claim 15, wherein the operating portion includes a light source.

19. The power tool of claim 15, wherein the operating portion includes a vacuum.

20. The power tool of claim 15, wherein the first tool terminal and the second tool terminal are substantially identical to one another.

21. The power tool of claim 15, wherein the housing includes a terminal portion that defines the first tool terminal and the second tool terminal, and wherein the terminal portion is integral with at least one of the main housing portion and the handle portion.

22. The power tool of claim 15, wherein the housing includes a terminal portion that defines the first tool terminal and the second tool terminal, and wherein the terminal portion is detachable from at least one of the main housing portion and the handle portion.

23. The power tool of claim 15, wherein the accessory attachment further includes a flexible portion extending between the accessory terminal and the operating portion.

24. The power tool of claim 15, wherein the operating portion is pivotally coupled to the accessory terminal.

25. A method for operating an accessory and a power tool, the accessory including an accessory terminal and an operating portion, the power tool including a first tool terminal, a second tool terminal, and a battery including a battery terminal, the method comprising the acts of:

selectively engaging the battery terminal with either of the first tool terminal and the second tool terminal to provide electrical power to the power tool and to the other of the first tool terminal and the second tool terminal; and

engaging the accessory terminal with the other of the first tool terminal and the second tool terminal to transfer electrical power between the accessory and at least one of the battery and the power tool.

26. The method of claim 25, wherein the first tool terminal and the second tool terminal are provided on a handle portion of the power tool, and wherein the selectively engaging act includes orienting the battery to extend from the handle portion in a first direction, and wherein the engaging act includes orienting the accessory to extend from the handle portion in a second direction that is substantially opposite the first direction.

27. The method of claim 25, wherein the selectively engaging act includes moving the battery in a first direction with respect to the power tool, and wherein the engaging act includes moving the accessory in a second direction substantially opposite the first direction with respect to the power tool.

28. The method of claim 25, wherein the operating portion includes a light source, and wherein the method further comprises the act of lighting a work piece with the light source.

29. The method of claim 25, wherein the operating portion includes a vacuum, and wherein the method further comprises the act of removing debris from a work piece with the vacuum.
