It can be used as a battery . When the battery is
fully charged, pin 6 of operational amplifier A outputs high level, and the light-emitting diode VL goes out. When the battery voltage is
insufficient, VL lights up.
By adjusting the potentiometer RP, the size of the sampling voltage can be changed to monitor how low the battery drops before VL goes out
.
