Let me first clarify that I bought this battery at seller CABLE AND PHONE. First, the product use instructions seemed dubious because poorly printed, some characters were barely legible. Then, leaving the product from its box, a hesitation ... The battery does not seem identical to one delivered with my D300s. Verification, in fact, the products are different !!!! Plastic is different, the police in which is written NIKON differs slightly, the finishes are not as good on the received product. But especially this does not have the NIKON hologram and weighs 73grammes, against 81 for the original product! At that price, indeed, it was too good to to be totally honest. To flee.
