Camera Nickel-cadmium Battery Discharger Circuit is shown in the graph below.After preshing AN, J1 will actuate. At this time, because the voltage on the end of the battery is high, the potential,which has been divided by R1 W1 and then been injected into the baseVT is also high.Both VT1 and VT2 will breakover,and J1 will actuate to protect itself. The battery discharges mainly through IC1, R2, and the indicator light D2 will be on. When the battery voltage drops till it is insufficient for VT1 to breakover, J1 will discharge until its normally open contact disconnects. And when its normally close contact gets through charging circuit A,battery charging begins.
