6 Frequently Asked Questions about “Battery full charge switching circuit”
How do I charge a real battery?
Connect the Power and Real Battery: Take off the variable power source and swap it out with the battery you wish to charge. To activate the circuit, connect the main power supply to the transistor's input (TR1). From this moment on, the circuit assumes control: The battery will start charging on its own.
Can an overcharging battery cut off circuit be combined?
In this series, an automatic overcharging battery cut-off circuit and an automatic over discharging battery cut off circuit have been designed. However, it is not possible to combine those circuits together to automatically cut off the battery for both overcharge and overdischarge cases.
