No, what _you_ are telling him is not practical. That's the bottom
line. See my other followup for a simple and easy way to check them.
I musta missed your post. Please post it again.
All I saw from you was a way to get an approximate value for the
capacitance by timing a low current discharge. That's hardly what the
OP asked, "want to check them if they are up to
their claimed stsndard." In almost all the applications I can think
of, leakage or ESR might be CRITICAL parameters. I don't know the
failure mode for over voltage, but if they're surplus, that might also
be a thing to test for.
This brings up two of my pet peeves:
1)people don't ask the question they want the answer to.
Often they don't even know what to ask. An "overkill"
answer at least gives them a framework to hang more questions on.
(ending sentences with prepositions is not an error...it's a skill)
2)Very smart and experienced people make grand assumptions about what
the OP meant and launch into specific solutions. (Maybe I'd do better if
I put the psychic hotline on speed dial...)
Then they defend their position against more open-minded discussion.
One of the greatest impediments to communication is believing that you
understood the other's position.
A lot of this could be avoided if people would talk a little about their
application when they ask vague questions.
