ABSTRACT:
In various embodiments, to avoid having to plug in the speakerphone, the speakerphone may be powered with a battery. In some embodiments, the speakerphone may exchange a discharged battery with a charged battery on a charging stand. In some embodiments, a charging stand, with a battery releasably coupled to the charging stand, may be configured to receive a second battery from a speakerphone. In some embodiments, the speakerphone with the first battery may be placed onto the charging stand to engage the charging stand. The charging stand may determine if the first battery on the speakerphone needs to be exchanged (e.g., if it is charged below a predetermined limit). If the battery needs to be exchanged, the charging stand may exchange the first battery with the second battery by disengaging the first battery and engaging the second battery with the speakerphone.
