The electronic circuit draws only 1ua of current in standby mode and jumps to only 20ua when flashing, so it Practical LED Indicator And Flasher Circuits | Nuts ... If you have an application where you need to drive this basic flasher circuit from a 3V battery, you can do so by using the 3V battery to directly drive a super efficient voltage doubler circuit based on the popular ICL7660 IC, and use the 6V output of the doubler (connected directly across C2 in Figure 19) to power the 6V version of the Figure ... THREE VOLT LOW BATTERY VOLTAGE FLASHER LED_and_Light ... This circuit is designed to monitor two alkaline cells (3v) that form the battery often used in portable electronic equipment. It use an inexpensive IC from Panasonic that is connected to an efficient LED flashing circuit. When the battery voltage drops below a certain point the circuit flashes the LED. Source: discovercircuits Battery and Charger Circuits – Page 2 – Circuit Wiring ... Here is the circuit diagram of low battery indicator from silicon chip electronics. This simple circuit lights LED1 when the battery voltage drops below the setting set by trimpot VR1. In effect, VR1 and associated resistors bias Q1 on which holds Q2 and the LED off. Circuit 3v Low Battery Voltage Flasher Circuit Hobby Circuit Many battery powered devices use two AA alkaline cells. Often you will not know when it is time to replace the batteries until the device powered by them actually stops operating. The circuit below can be connected to a 3v battery, to give you some warning when the battery is nearing its end of life. It will flash a LED when the battery voltage drops to about 2.4 volts.
