THREE VOLT LOW BATTERY VOLTAGE FLASHER
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. In the off state the circuit draws only 1uA, while in the active flashing state it draws 20uA. Published in EDN, Jan 2, 1997

Simple Circuit Safely Deep Discharges NiCd Battery: 04/29/99 EDN-Design Ideas / (added 11/05) Nickel-cadmium (NiCd) batteries can possess an undesirable memory effect due to partial discharges. The remedy is a complete discharge before charging again. Figure 1a shows a simple circuit that performs this feat. Although relatively straightforward in concept, the circuit has three redeeming features: It receives its power from the battery undergoing the discharge; after the battery is fully discharged, the current drain is only approximately 4 µA, which is usually...
