CHARGER CIRCUIT

1.5 Volt Battery Charger series and 9 Volt | charger circuit ( battery charger ) is very simple and relatively low cost by using components that many are sold on the market. This charger circuit using a transistor as a source of current is constant. Voltage through a pair of 1N4148 diode bias voltage to the base medium power transistor BD140. While the base-emitter voltage of transistor sanagt relatively stable . currents around 15mA 45mA charging the battery with the switch closed condition. This is consistent with a rechargeable battery with a voltage of 1.5V and 9V. You can use a transformer with a secondary output 2V ac / 0.5 A. The series Battery Charger 1.5 Volt and 9 Volt:
