A wireless mouse suitable for use with a computing device, and method of using such a mouse. The mouse includes a housing, electronics within the housing for sensing movement of the mouse and wirelessly communicating with the computing device, at least two batteries within the housing, a device for monitoring a power level of each of the batteries, and a device for switching between the batteries to deliver electrical power from one of the batteries to the electronics. Each battery is adapted for individually powering the electronics, and the switching device operates to switch from a first of the batteries to a second of the batteries when the power level of the first battery sensed by the monitoring device drops below a preset depletion threshold value.
