Claim 15:
16. An electrical combination comprising:
an electrical device including a device housing and a device terminal, the device housing including a device support portion, the device support portion including a first rail/groove interface and a second rail/groove interface, the first rail/groove interface approximately parallel to the second rail/groove interface;
a first battery pack including a first battery pack housing including a first pack support portion for engagement with the device support portion, the first battery pack housing having a first battery pack width, and
a first battery cell supported by the first battery pack housing, power being transferrable between the first battery cell and the device terminal when the first battery pack is connected to the electrical device,
the first pack support portion including a third rail/groove interface and a fourth rail/groove interface, the third rail/groove interface and the fourth rail/groove interface configured to mate with the first rail/groove interface and the second rail/groove interface of the device support portion, the first pack support portion defining a first interface width between the third rail/groove interface and the fourth rail/groove interface, and
a second battery pack including a second battery pack housing including a second pack support portion for engagement with the device support portion, the second battery pack housing having a second battery pack width that is greater than the first battery pack width,
a second battery cell supported by the second battery pack housing, power being transferrable between the second battery cell and the device terminal when the second battery pack is connected to the electrical device,
the second pack support portion includes a fifth rail/groove interface and a sixth rail/groove interface, the fifth rail/groove interface and the sixth rail/groove interface configured to mate with the first rail/groove interface and the second rail/groove interface of the device support portion, the second pack support portion defining a second interface width between the fifth rail/groove interface and the sixth rail/groove interface, and
wherein the second interface width is approximately equal to the first interface width.
