12Vdc mobile battery charger circuit diagram can delivers up to 20 V output from the 12V car power supply, allowing a constant current charging […]

This is a car nicd battery charger circuit that can charge any Ni-Cd battery between 4.8 and 4.4 volts from a classic 12 Volts car battery. The charging current is constant it can be selected from the values ​​of 50 to 120 mA by the selector S.

Note that the stability is observed when the load current and will change slightly of the supply voltage. Likewise, the fact is usually overlooked, […]
