| Abstract: | The rechargeble batteries are used for backup power internal electrically equipments and instruments.But batteries lifetime usually is shorten by overwork and then malfunctions of equipment are induced.To avoid the complexion described above,the protection circuit against overwork is designed.It is based upon the voltage comparator and regulator.It will light up a red LED when the volume of the batteries discharged close upon 50%;It will switch off the load automatically when it discharged closing to 80% of their energy capacity,thus overwork of batteries can be avoided and lifetime may be extended. |

| Keywords: | backup-power overwork switch off secondary cell load |
