I am going to try another approach with my radio.
I have went through 4 dead batteries, and each one that I have used has turned my radio (after a few seconds of opeation) into an high-pitched oscillator that slowly decreases in pitch.
This makes me think that low voltage is not a good way to go.
I have been buying low priced batteries from the dollar store in the past, and I wonder if I could get at least 6 hours of operation out of them. It would be a royal pain for me to buy the more expensive (duracell, energizer, etc) batteries and find out they die after 1 hour.
My radio does not use alot of current. The absolute highest current consumption would be about 20ma because I am feeding the voltage to the LED through a 470 ohm resistor. All the other pull-up resistors have higher values.
so what is the best 9V square battery to buy if I am looking for long time voltage stability?
