I have used LTV3401 as a comparator for low battery indication. Current - Quiescent (Max) is 950nA. But costs 2USD
Is it possible to use the transistors for the low battery indication. But the circuit should consume very low current. COST EFFECTIVE
Input voltage: 9V (Battery 6F22)
Output will be fed to the microcontroller input pin to detect the voltage as 0 or 1. So that I can able to display the LOW BAT on the display.
