GoPro Hero 8.7,6,5 Black Batteries

I recently bought two new GoPro Hero Black Batteries from GoPro. Model #SPJB1B.

I have charged them up with my GoPro charger. They Show Green so I know they are fully charged. However the camera does not seem to respond when I install the batteries and try to turn it on. Can someone enlighten me what I may have done wrong?
