AUDIO CONTROLLER

SOUND CONTROLLERFrom Nickel-cadmium batteries with a life expectancy of 100-200 cycles of charge-discharge. Discharge below 1V per cell leads to a sharp reduction in the duration of battery life. How to control a threshold voltage of discharge of the battery during operation? To have with you the measuring device is inconvenient. It functions best to hold the indicator — sound generator with a silicon Zener diode. Its voltage stabilization determines a controlled level of discharge.
