This circuit can be used as nickel cadmium and dry battery's charging and also used as genernal low voltage DC power. This circuit is composed of charging and DC output part.K2 is fast and slow charging choice switch.R2 and R3 are current limitting resistors which can alter charging current value.Usually, quick charging is controlled in 4 h or so, slow charging is about 14 h.NA，ZD consititute test circuit.Please install the batteries which will be charged before the charging.It's normal if the ZD has no light or has slight lihgt when AN is pressed.It's charged fully and can be used by electrical appliances if ZD has sparked for over 10S when the AN is pressed and chagring time meets the requirement.
