Small-size battery charging circuit which can choose charging time is shown in the above picture. The charger has the required constant current source digital circuit timer for charging safely. It can be used to charge 12 pieces of nickel-cadmium batteries. There are three grades of charging time for choice, and they are 5 hours, 14 hours, and 24 hours. The voltage adaptor of 15V outputs voltage supply the power for the circuit. 15V DC voltage is sent to the two constant current sources to charge the battery. In addition, IC3 (7810) provides the stable 10V power voltage for the timer。
