power on the device.
Actually, it is. The oxide breaks down whenever the capacitor
isn't
powered, but it is an exponential decay effect. Leaving something
powered off a short while doesn't let it break down too much, and when
you power it up again, the oxide reforms a little bit, back to where it
is supposed to be.
If you take a 25V electrolytic capacitor, and use it at only 6V for a
long time, then apply 25V suddenly, you're likely to damage it.
The claim was made that running the device regularly
keeps it in
operating condition and that *not* running the device regularly
accelerates the deterioriation.
Yes.
