Let me begin by saying that I'm not stupid. In fact, I'm extremely intelligent (and modest ). My IQ has been measured somewhere above 70 in fact. Anyway, today after flying, I put one of my two batteries on the charger (the cooler of the two). An hour or so later I returned and was surprised to see no lights flashing on it. It had apparently charged much faster than I expected it to. I removed it from the charger and hooked up the second battery. As I did so, I pressed the button on the first battery to verify a full charge. Only one light came on. It was my oldest battery so I thought it must be dying and could no longer hold a charge. It was at that moment I noticed the second battery on the charger wasn't flashing at all! Crap! My charger must be bad or.....yep! The charger wasn't plugged in to the wall! As I said earlier, I'm not stupid but I can be quite an idiot sometimes. Anyone else care to embarrass themselves by admitting to some bonehead thing they've done? Don't leave me hanging here by confirming I'm the only idiot!
