I just discarded a pile of old versapak 7.2v tools, keeping only a few
flashlights and a vacuum.
I have about a dozen vintage batteries. They all work, but I expect some
are pretty marginal. Since I have more than I need, I would like to test
them and get rid of the worst.
Any way to do that? I suppose I could charge them and see how long they
last in flashlight, but I was hoping for something simpler.
