Query: Batteries no good

I bought these for my Sony FS100. I purchased three of them for good measure. As soon as they arrived they appeared to be in Sony packaging, but on closer inspection the Son'y label was different from the original batteries I had already. When I charged each of them for over a day I figured they were done. When I placed them in the camera it stated that the batter was at 86%. I thought it was a joke, so I placed them back on the charger and when it was charged again put them back into the camera... 87%. All three of them could not hold a charge. I used them in the field and when it was around 50% the battery died... all 3 of them. If this was a problem with one I could expect that, but combining the labeling with how they charged and performed, fake!
