Low Battery Indicator Circuit Using Two Transistors Only

Last Updated on May 17, 2026 by Swagatam 207 Comments

lowbatteryindicatorcircuit 2

In the following post I have explained a simple low battery indicator circuit by using just two inexpensive NPN transistors. The main feature of this circuit is its very low stand by current consumption. The Circuit Concept We have so far seen how to make a low battery indicator circuits using a 741 IC and […]
