A sensing circuit for metal object includes a resonating element, a power supply circuit, and a determining circuit. The resonant element is coupled to the power supply circuit and the determining circuit. The power supply circuit drives the resonating element to generate an oscillation, and the determining circuit determines the position of the metal object relative to the resonating element according to the energy change of the resonating element.

A power supplying method is adapted to supply power to any one of external electronic devices with voltage-stabilized capacitors of different specifications. The power supplying method includes: generating a periodic signal; periodically turning on and off a load-switch circuit by the periodic signal to enable the load-switch circuit to periodically charge and discharge the voltage-stabilized capacitor; generating an enable signal following the periodic signal; continuously turning on the load-switch circuit by the enable signal to enable the load-switch circuit to supply the power to the external electronic device according to a flag signal; and detecting the amount of a current supplied to the external electronic device by the load-switch circuit to determine a level of the flag signal. During periodically charging and discharging the voltage-stabilized capacitor, the amount of the current supplied to the external electronic device is gradually decreased.

A battery includes a casing, a battery pack, and at least two electrical connecting assemblies. The casing includes an inner space and plural contact planes. Vertical directions of the contact planes are different. The battery pack includes a battery cell disposed in the inner space, and the battery cell includes a positive and a negative electrodes. The electrical connecting assemblies are electrically connected to the positive electrode and the negative electrode respectively, so as to transmit power between the battery pack and an electronic device. The electrical connecting assembly electrically connected to the positive electrode is arranged on at least two of the contact planes, and the electrical connecting assembly electrically connected to the negative electrode is arranged on at least two of the contact planes. If power supply in one certain direction is interrupted, the battery transmits power in the other directions, thereby avoiding power supply from being interrupted.
