Abstract
A medical instrument is disclosed. The medical instrument includes at least one electrical contact, a radio frequency (RF) generation circuit coupled to and operated by the battery and operable to generate an RF drive signal and to provide the RF drive signal to the at least one electrical contact, a battery discharge circuit coupled to the RF generation circuit, a processor coupled to the battery discharge circuit, and a memory coupled to the processor. The memory stores computer instructions that when executed cause the processor to monitor battery capacity and send a signal to the battery discharge circuit to discharge a battery coupled to the battery discharge circuit when the battery capacity falls below a predetermined threshold.
