I wrote a simple Java program to first connect the charger for a few hours, then disconnect the charger and connect the current sink while polling the voltage detector every few seconds. It then calculates the capacity once the discharge is complete.

I wish my definition of "
simple" matched yours! This is something I would have to invest a big pile of time & learning to accomplish (not that there's anything wrong with that).
Though I will say: thanks, because your post motivated me to decide I will study electronics a bit more this winter.
