when using super cap how do you prevent overvoltage ~5.5v? As NiCad orig's age (dried out?) the internal resistance gets large and the terminal voltage rises as high as 7-8v resulting in IC damage!??
Caps don't charge any higher than the voltage applied to them. A 100V cap just means it can handle up to 100v before it fails. But if you only charge a 100v cap with 3v, then it only has 3v in it.
Think of voltage like air pressure. Make a tank with 1/2" thick steel that can hold 10,000 psi. But only pump 3 psi into it, and it only has 3 psi in it.
