The charger of the figure is composed of three components, it is the simplest charger, this circuit is the capacitor current limiting charging circuit, the charging current is decided by the current limiting capacitance C, both the charging of one battery or more than a dozen batteries, the charge current will not change, D1 and D2 are the rectifier diodes, the current limiting capacitance need to choose the >400V non-polarity capacitor, the charge current should not exceed 100mA, if you want to charge the 500mAh number five nickel cadmium battery, the charging time is about 6 hours.
