lightning detector

Apart from an academic point of view - why?
A couple of batteries should last practically the shelf life.

why?  I have been building a weather station from bits over the years,
the lightning
counter I want to pot in resin and dont want to fiddle with batteries.
I could have a solar panel/supercap powering a conventional circuit but
with so much electricity in the ether surely theres a reliable way to
induce some power to blink an led.

Just build a proven low power circuit, power it from some lithium
cells, and pot the whole thing. It would not be unreasonable to expect
a 10 year battery life from such a setup.
If you really want, pot the batteries in a separate pack. Batteries die
in 5 years?, no problem, snip the wires and install a new pack. My
guess is you'd spend a lot less time installing a new battery pack
every 5 years than you would trying to design some self powered system
to work reliably.

You can get industrial primary lithium C or D size cells which have an
incredible energy density and super long life.

What will your "counter" be powered from?

Just wondered if one of those $5 solar garden lights would be a good
power source for your project
