I just got a new RC40 today. I plugged it in to charge it, and at first, the four LEDs blinked sequentially as they're supposed to; the manual says it would take 3 1/2 hours for a full charge.
After 30 minutes or so, I noticed that the 4 LEDs were now all on without flashing, so I assumed that the light had a partial charge when it was shipped. I unplugged the charger, and tried to turn the light on, but nothing happens. No power at all. When I plug the charger back in, the 4 charging LEDs are all lit. No sequential flashing.
Do I have a defective unit, or am I doing something wrong? I will leave the charger plugged in for a few hours, and check it again, but it seems strange that the charging LEDs would indicate a full charge and yet the light will not turn on at all.
Thanks for any advice anyone can give. (I purchased this from Amazon, so an exchange should be easy if the unit turns out to be defective).
