1. 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 extending along a first axis and a second rail/groove interface extending along the first axis, the first rail/groove interface approximately parallel to the second rail/groove interface;
a first battery pack including:
a first battery pack housing, the 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,
a first battery cell supported within 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 extending along a second axis and a fourth rail/groove interface extending along the second axis, 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, the 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,
a second battery cell supported within 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 including a fifth rail/groove interface extending along a third axis and a sixth rail/groove interface extending along the third axis, 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,
wherein the first interface width is approximately equal to the second interface width, and
wherein the second battery pack width is greater than the first battery pack width.
