Is the battery dead already?
You can also hold down the power button while placing into the charger...ive seen this give a much faster result in testing the battery charge as opposed to simply placing in charging and seeing if anything happens. .I had the same issue and holding down the power button and placing it in the quick charger. Charger came on like it was trying to read the battery, then I got a blinking green light on the battery itself. Took the battery out and tried again, red light on the charger within a few seconds, dead battery.
