In the absence of accurate indication of the power of the battery and in the description and the picture, I still indicated to be controlled as for Fuji x10 and on the basis of a buyer who indicated having received 800 mAh battery, no further comment will indicating the intensity of the product. I received (that said very quickly) marked a 3.7V 650 mAh battery which does not match the original battery Fuji 3.7 V and 1000 mAh .The mention of power is clearly indicated received on battery while it does not appear at all on the picture Amazon .This would mention it was deliberately erased to fool the potential buyer? This also raises the issue of the credibility of filed comments.
