1. A battery for electronic equipment, comprising:

  • a rechargeable power supply; and

    a battery chip including;

    an oscillation circuit configured to generate a sine wave signal, after the rechargeable power supply starts to supply power to the electronic equipment;

    a reference voltage generating circuit configured to generate a predetermined reference voltage; and

    a comparator having first and second input terminals connected respectively to the oscillation circuit and the reference voltage generating circuit, and an output terminal connected to a predetermined transmitting pin, the comparator being configured to generate a customized signal based on comparing the sine wave signal and the predetermined reference voltage,wherein;

    the rechargeable power supply is configured to supply power to the electronic equipment; and

    the battery chip is configured to detect whether the rechargeable power supply has started to supply power to the electronic equipment and, when a detection result is that the rechargeable power supply has started to supply power to the electronic equipment, transmit the customized signal to the electronic equipment through the predetermined transmitting pin.
