ABSTRACT:
A battery checker circuit comprises a voltage divider connected across a storage battery and including a voltage detection resistor. The voltage developed across the detection resistor is sensed by a transistor, which conducts to energize a display element when the battery voltage is above a reference voltage. For a battery voltage below the reference voltage, the transistor is rendered nonconductive to deenergize the display element. The illumination or extinction of the display element indicates whether the battery voltage is above or below the reference voltage.
