1. A surgical system comprising:
a handpiece comprising:
a body, and
a handpiece connector operatively coupled to the body and comprising a first coupler; and
a battery comprising
a housing,
a rechargeable cell for storing an electric charge, and
a battery connector operatively coupled to the housing and comprising a second coupler configured to rotatably engage the first coupler;
wherein the second coupler is further configured to receive the first coupler along an axis at an initial radial position where relative axial movement between the battery and the handpiece is permitted, and to permit rotation of the battery relative to the handpiece from the initial radial position to a first secured radial position and a second secured radial position, wherein relative axial movement between the battery and the handpiece is constrained in the first secured radial position and in the second secured radial position.
