I make my own BCR's (way to expensive to buy them in the States and get them shipped to me here in Australia now), and when I am finished, I want to test them to make sure the supercap is up to the task.
In the past I have found a very small number of these supercaps will not take a full charge, or they lose their charge within minutes of the charging cycle.....these I class as "duds", and they get discarded.
I buy them in lots of 50, and they work out at under $8 each Australian ($4 US), delivered.
Hence my need to "test" them before they go into a loco.
