As shown in the figure is an automatic charger circuit for nickel-cadmium batteries composed of CD 4001/CD4541.
This circuit is specially designed for charging No. 5 and No. 7 cadmium nickel batteries. It has the characteristics of automatic charging and constant current charging. The circuit is shown in the figure. The circuit starts working after the power is turned on, and the internal counter counts the oscillator. When the count is full, the output level of pin 8 of IC1 flips and stops counting. If the M terminal of pin 10 is connected to high level, pin 8 will flip after the count is full, and then count again, and then flip again after the count is full, and so on.
