Charger circuit equipped with a regulator circuit output voltage

The circuit charger is equipped with voltage output settings , so that we can regulate how much voltage to charge the battery. And the settings using the potentio making it easier for us managing voltage up to a mV. See charger circuit below :
Adjust the circuit by setting the 500 Ohm resistor while it is attached to a fully charged battery.
You can use the circuit to charge :
  • Cells battery
  • Wet Accu
  • Dry Accu
  • Nicad battery
  • Solar battery
