With supply currents below 100nA you can assume that you are likely
to be limited by the self-discharge using coin sized LiMnO2 cells
(e.g. a CR2032 is specced in the order of 100-300nA self-discharge).
For the smaller cells, you have to check which one is larger, but
they are of the same order of magnitude.
