In accordance with the present invention, an improved battery pack is employed. The battery pack includes a housing with opposing walls, a plurality of cells disposed within the housing, at least two terminals electrically connected to the cells, a latching mechanism disposed on each opposing wall for latching the battery pack to a cordless device, each latching mechanism including a latch and a button disposed on the wall for moving the latch between unlatching and latching positions, the latching buttons being disposed along a first plane, the first plane being substantially vertical, wherein the number of cells disposed along the first plane is smaller than the number of cells disposed along a second plane substantially parallel to the first plane. The battery pack may also include a stacked cell disposed on the plurality of cells. The stacked cell may be disposed along the first plane. However, the stacked cell is not included in the number of cells disposed along the first plane.

What is claimed is: 1. A battery pack comprising: a housing comprising a first portion having a first floor and first and second walls connected to the first floor, and a second portion having a second floor and third and fourth walls connected to the second floor, where the first and second floors
What is claimed is: 1. A battery pack comprising: a housing comprising a first portion having a first floor and first and second walls connected to the first floor, and a second portion having a second floor and third and fourth walls connected to the second floor, where the first and second floors are non-coplanar, the first and second portions defining a cavity, the first and second floors being disposed underneath the cavity; a plurality of cells disposed within the cavity of the housing; at least two terminals electrically connected to the cells, the at least two terminals being disposed above the cavity; and a first latching mechanism disposed on the housing for latching the battery pack to a cordless device, said first latching mechanism comprising a first latch and a first button connected to the first latch for moving the first latch between unlatching and latching positions. 2. The battery pack of claim 1, further comprising a second latching mechanisms disposed on the housing for latching the battery pack to the cordless device. 3. The battery pack of claim 2, wherein the second latching mechanism comprises a second latch and a second button connected to the second latch for moving the second latch between unlatching and latching positions. 4. The battery pack of claim 1, wherein at least the first button is disposed on the second portion. 5. The battery pack of claim 3, wherein the first and second buttons are disposed along a first line located at a first distance from first floor plane. 6. The battery pack of claim 5, wherein distance between the first and second buttons along periphery of the housing is smaller than distance between two points along periphery of the housing, the two points being contained within a second line parallel to the first line and located at the first distance from the first floor plane. 7. The battery pack of claim 3, wherein number of cells disposed along a first plane between the first and second buttons is smaller than number of cells disposed along a second plane substantially parallel to the first plane. 8. The battery pack of claim 7, further comprising a stacked cell disposed on the plurality of cells. 9. The battery pack of claim 8, wherein the stacked cell is disposed along the first plane. 10. The battery pack of claim 9, wherein the stacked cell is not included in the number of cells disposed along the first plane. 11. The battery pack of claim 1, wherein the first and second portions comprise substantially non-coplanar surfaces. 12. The battery pack of claim 11, wherein distance between the second portion surface and a center plane dissecting the housing is smaller than distance between the first portion surface and the center plane. 13. The battery pack of claim 11, wherein the first portion surface is substantially vertical. 14. The battery pack of claim 11, wherein the second portion surface is substantially vertical. 15. The battery pack of claim 11, wherein the second portion surface is inclined. 16. The battery pack of claim 11, wherein at least the first button is disposed on the second portion surface. 17. The battery pack of claim 1, wherein at least one of the cells is horizontal. 18. The battery pack of claim 17, wherein at least one of the cells is vertical.
