I need a low battery indicator (that draws very little power) for a circuit I am using. The battery bank I expect to peak out around 18 volts or there abouts, and eventually decrease to about 6 volts before my peripheral devices crap out. So, does anyone have any idea how to make a low cost, simple low battery monitor that can be powered from ...Low Battery Indicator Circuit Diagram
Low Battery Indicator Circuit Diagram: When JP1 and JP2 are in their other position, there is no on off indication; the quiescent current then drops from about 4 mA to a few µA. If this condition is selected, the connections of D2 must be changed over (as shown in dashed lines).Battery low voltage alarm indicator circuits
Simple Battery Low Voltage Alarm Indicator Circuits. This circuit designs to come to apply to volt since 3 15V. The LED will begin to show, we can adjust with VR1. When voltage decrease down more location dot keeps LED bright immediately. The electronics part a little also just transistor BC547 and other.Simple battery charger circuit and battery level indicator ...

The Design Idea in Figure 1 indicates a low battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all discrete design, this same approach seemed more in keeping with the spirit of the project than the use of a single sourced integrated circuit.
