Abstract

A battery pack and a method for connecting a battery pack to an electronic device to power to the electronic device (e.g., a headlamp, a flashlight, a flood light, a drill, a driver, etc.). The battery pack includes a generally cylindrical housing defined by an arcuate sidewall extending between a first end surface and a second end surface and defining an interior cavity configured to support at least one battery cell (e.g., a lithium-ion battery cell). The battery pack includes a first insertion alignment member engageable with a first battery alignment member of the electronic device in order to facilitate insertion into a receiving portion of the electronic device in a first direction and a second insertion alignment member engageable with a second battery alignment member of another electronic device in order to facilitate insertion into a receiving portion of the other electronic device in a second direction.

First claim

What is claimed is:

1. A battery pack comprising:
a housing extending along an axis;
a battery cell positioned in the housing;
a first insertion alignment member disposed on the housing guiding insertion of the battery pack into a first electronic device in a first direction relative to the axis; and
a second insertion alignment member guiding insertion of the battery pack into a second electronic device in a different, second direction relative to the axis.

2. The battery pack of claim 1 , wherein the first direction is a radial direction relative to the axis of the battery pack.

3. The battery pack of claim 1 , wherein the second direction is an axial direction relative to the axis of the battery pack.

4. The battery pack of claim 1 , wherein the first insertion alignment member cooperates with a complementary first alignment member on the first electronic device to guide insertion of the battery pack into the first electronic device.

5. The battery pack of claim 1 , further comprising battery pack terminals electrically coupled to the battery cell and operable to interface with and to electrically couple the battery cell to device terminals of each of the first electronic device and the second electronic device.

6. The battery pack of claim 5 , wherein the first insertion alignment member cooperates with a second lockout member on the second electronic device to facilitate engagement of the battery pack terminals with the device terminals of the second electronic device.

7. The battery pack of claim 1 , wherein the first insertion alignment member includes a groove or a protrusion.

8. The battery pack of claim 7 , wherein the housing has an axial surface, and wherein the groove of the first insertion alignment member is defined on the axial surface.

9. The battery pack of claim 1 , wherein the second insertion alignment member includes a groove or a protrusion.

10. The battery pack of claim 9 , wherein the housing has a circumferential surface, and wherein the groove of the second insertion alignment member is defined on the circumferential surface.

11. The battery pack of claim 1 , wherein the housing has a first surface, a second surface, and a sidewall extending therebetween, the first insertion alignment member being disposed on the first surface, the second insertion alignment member being disposed on the sidewall.

12. The battery pack of claim 11 , further comprising battery pack terminals electrically coupled to the battery cell and operable to interface with and to electrically couple the battery cell to device terminals of each of the first electronic device and the second electronic device, the battery pack terminals being disposed proximate an intersection of the sidewall and the first surface.
