This article describes the Battery Level Indicator (LM10). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: LM10.

Abattery level indicator circuitis depicted in theschematic diagrambelow. This circuit is designed for 9V battery operation, as this circuit will start dimming below 7V and will be completely turned off at 6V.? If you want theLED indicatornot to dimming but just abruptly turns off at below 6V, then you can remove R3, and change R1 to 330k.
