Simple Battery Monitor Circuit Diagram Using NPN Transistor BC547 | Car Battery Monitor Circuit
Diode:
D1 – 6V, 500mW Zener
D2 – LED (any color)
Circuit Description:
This circuit indicates a warning whenever the battery voltage falls below the level set by 10K pot. It can indicate that the battery is defective or needs charging if cranking drops battery voltage below preset “safe” limit.
