Abstract
An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.

An electrical combination comprising:
- an electrical device including a device housing and a device terminal, the device housing including a device support portion;
- 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 pack support portion defining a first support portion width, 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;
- 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 pack support portion defining a second support portion width, 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,
- wherein the first support portion width is approximately equal to the second support portion width, and
- wherein the second battery pack width is greater than the first battery pack width.
