1. A power tool battery pack receptacle comprising:
a cavity in which a portion of a battery pack is receivable, the cavity defined in part by a first wall, a second wall, and an intermediate wall coupled between the first wall and the second wall;
an insertion end;
a closed end opposite the insertion end along an insertion axis of the battery pack;
a rail coupled to the first wall and extending between the insertion end and the closed end, the rail defining a guide surface;
a groove defined between the intermediate wall and the guide surface of the rail, the groove having a lateral wall coupled between the intermediate wall and the guide surface of the rail; and
a tapered contact surface extending between the intermediate wall and the first wall, the tapered contact surface configured to engage a latch of the battery pack to tighten a connection between the battery pack and the battery pack receptacle, and
wherein, when the latch is in a locking position to secure the battery pack to the battery pack receptacle, the tapered contact surface pushes the latch away from the intermediate wall in a direction perpendicular to the insertion axis.
