observations after day 3:
1. my shorty Diamond batts don't make the PCC's red LED blink when fully charged, like other batts. the light just stays off.
2. one of my 3 shorty Diamonds (black w/ purple) is demonstrating the lack of contact with my clove coolcarts. i was able to pry up the center post of the batt, and make it function. i did notice, comparing the faulty one to the other two, that the center post seemed much more flexible on the faulty one. i wonder if something broke loose, resulting in the center post being supported only by the rubber gasket below it.
3. i made a perfect tool for remedying this: a push pin that has had the point bent back. i took nice pointy pushpin from my cork board, held it on my kitchen sink edge, and whacked it moderately with a hammer. this made the point curl back, so it's got a little hook to it. make sense?
