It uses 1 / 10 rated capacity ( 145 mA charging current) to charge for 14 to 16 hours. The charger charging current is about 170 mA, and the charging time is about 12 hours. The required components are: a transformer with power being about 10W and the secondary winding voltage between 12 ~ 15V; 7812 three-terminal voltage regulator integrated circuit; 4 IN4008 diodes ( or a 1A/200V bridge rectifier ), a 2200UF/50V electrolytic capacitor and a 0.1UF homopolar capacitor; a 56 ohm resistor; a battery box which can put four batteries; a piece of board, and many wires.
