Method and circuit for displaying battery remaining capacity of real-time clock and storage medium

The invention provides a method and circuit for displaying the remaining capacity of a real-time clock battery and a storage medium. The method is applied to the electronic equipment and comprises the following steps: receiving a startup signal of the electronic equipment; reading the voltage of a real-time clock battery based on the power-on signal; and determining the residual electric quantity of the real-time clock battery based on the voltage of the real-time clock battery, and sending the residual electric quantity of the real-time clock battery to a display device for display. According to the method and circuit for displaying the remaining capacity of the real-time clock battery, when the electronic equipment is started, the voltage of the real-time clock battery is read, the remaining capacity of the real-time clock battery is determined according to the voltage of the real-time clock battery, and the remaining capacity of the real-time clock battery is displayed. In this way, a user can know the rem
