When I bought this battery I received an extremely convincing counterfeit complete with hologram seals etc.... However when I used them the battery would work well for while and then suddenly die. I would recommend buying from an authorized reseller like BandHphotoVideo. The price was comparable and you are guaranteed a genuine product.
Hi Rick I bought this battery for my camera and I can give testimony that is original and working properly. A few days ago I lost one of the two I have and will go back to buy this battery. I recommend it.
They are either of the real thing or somebody went through a lot of trouble to make the exact same packaging and to make them function the same. By all appearances and all functionality these look to be the real thing. I was hesitant as well because those older posts worried me. But now after having made this purchase I'm not worried anymore.
