Wireless charging systems and methods for wirelessly charging batteries for powering surgical instruments. A wireless charging device includes a housing defining wireless charging bays for receiving and charging multiple surgical instrument batteries simultaneously. Power transfer coils and RF antennas are disposed in the housing, with each of the wireless charging bays being associated with a different power transfer coil for wirelessly charging a received battery and with a different RF antenna for wirelessly communicating with the received battery. The RF antennas are each configured to communicate in a same frequency band. The wireless charging device is configured to communicate with a battery received by a first of the wireless charging bays using the RF antenna associated with the first wireless charging bay during a first period while preventing the RF antenna associated with a second of the wireless charging bays from communicating with a battery received by the second wireless charging bay. Responsive to the first period elapsing, the wireless charging device is configured to communicate with the battery received by the second wireless charging bay using the RF antenna associated with the second wireless charging bay during a second period while preventing the RF antenna associated with the first wireless charging bay from communicating with the battery received by the first wireless charging bay.
