Zapper Refurbisher Ni-Cad Battery Circuit Diagram. Batteries and Nickel Cadmium, or simply Ni-Cad NiCad NiCd or sometimes do not work as expected, has no voltage or current, can not be recharged, it means that the battery is internally shorted or partially damaged. You can retrieve this battery in many ways, either by chemical or electrical recovery. One is simpler and recondition the Ni-Cad battery using a zapper circuit.
This circuit restores the Ni-Cad battery short circuit, forcing a high current flow to burn the dirt inside. The resistance of 120 ohm per 10W is used to limit the load current of the capacitor. After zapping the battery goes to the load position, the charging process will take a long time and is indicated by the LED, which will gradually increase the brightness intensity until stable, so when the battery is fully charged.
The power supply for the circuit can be made from a small transformer 350 mA to 1 A with a half-wave rectifier or full wave.
