How do I know if my battery is full?

Both LEDs will glow indicating the battery is full. When its voltage falls on 12.3V Green LED will go off indicating that the battery is half. Red LED will deactivate when the voltage of the battery falls on 12V indicating that the battery is low and needs to be charged. Before using this circuit some adjustments are needed initially.

What does a battery charging circuit do?

This circuit indicates a buzzer sound when the battery is fully charged. It can be used with all kinds of batteries of different voltages. There are a lot of automatic battery chargers available on the market. They will stop your battery from getting charged once it is full but they lack the ability of audio indication.

How to use a battery op-amp?

Set the voltage of the variable supply exactly the same as the voltage of your battery. Adjust the variable resistor of the op-amp until the LED turns on. That will be the preset value for your battery. Now the adjustments are done, you can connect your battery under charge with this circuit and use it.
