Abstract
A battery discharge circuit, used to couple a battery to an electronic device, includes a battery protecting module and a voltage adjusting module. The battery protecting module detects an output voltage of the battery, compares the output voltage with an end voltage of the battery, and selectively discharges the battery or not in response to the comparison result. The voltage adjusting module compares the output voltage with a work voltage of the electronic device, and selectively directly outputs the output voltage or boosts the output voltage first and then outputs the boosted output voltage.
