Abstract

A battery powered device that includes a battery pack having a fuel gauge to display a state of charge of the battery pack. The fuel gauge is located on the battery pack such that when the battery pack is engaged with the battery powered device the fuel gauge is visible through a window provided on the housing of the device.

Claims

1. An electrically powered device comprising;

a. a device housing having an actuator to energize the device and defining a window;

b. a battery pack selectively engageable with a portion of the device housing and including a battery pack housing within which at least one battery cell is disposed; and

,

c. a fuel gauge disposed on a portion of the battery pack housing such that when the battery pack is engaged with the device housing, the fuel gauge is registered with and visible through the window.

2. The device of claim 1 wherein the battery pack includes a latching mechanism to selectively secure the battery pack to the housing wherein the latching mechanism includes at least one button such that upon actuation of the button the fuel gauge displays a condition of the battery pack.

3. The device of claim 1 wherein upon actuation of the actuator the fuel gauge displays a condition of the battery pack.

4. The device of claim 1 further comprising a second actuator such that upon actuation of the second actuator the fuel gauge displays a condition of the battery pack.

5. The device of claim 1 wherein the device is a handheld battery powered device.

6. The device of claim 5 wherein the device is a handheld battery powered tool.

7. The device of claim 1, wherein the device is a drill.
