Warning!!!
Don't know if it's something unique to my USB port/PC, but I've had a second battery fail after leaving my camera hooked up to the USB port (but turned the camera off after transfer).
Put the battery on the charger and the charger's LED doesn't even light up. Tried freezing the battery, but no luck. Cleaned the contacts with a pencil eraser. The first failed battery was a Nikon battery and got Wolf to replace it. This one was my backup Eveready and it's failed the same way.
