An electronic lock includes a lock mechanism, an actuator coupled to the lock mechanism and configured to lock and release the lock mechanism, and an actuator control circuit coupled to the actuator. The electronic lock also includes a battery electrically coupled to the actuator, a super capacitor electrically coupled to the battery, and a processor coupled to the actuator, the battery, and the super capacitor. The processor is configured to selectively receive power from the battery and the super capacitor, wherein the processor receives power from the super capacitor when a state of charge of the battery is below a predetermined voltage threshold, and provide control signals to the actuator control circuit to control operation of the actuator.
