My sweet chrome shorty suddenly refused to cooperate with my wall charger. No blinking LED, the charger light doesn't change to red, nothing. Everything was fine for three weeks, and then--it just won't do it. I tried unplugging the charger from the wall to reset it, I let the battery rest overnight, I tried talking to them both, nada. The wall charger works fine with my other batteries, but the shorty will only charge on my USB charger. Does anybody know why this is happening?
