Query: Didn't work for me

I also just bought this charger with 4 Sony batteries, and am confused. I thought the instructions said the light turns green when they are finished charging, but it never has. I keeps going off, then I jiggle the charger in the socket, and it goes on again. I have never had a green light, and when I tried installing them in my camera, it says they are half charged. All I get is a yellow light, or no light, and my camera never says they are fully charged. I've tried several outlets in my house, same thing.
