I saw she was announced as the original, for an autonomy of 900 photos! Personally, I have exhausted all 2 after 300, max 400 (with D7100) as well as the original one, in the first two uses! Yet I do not use the screen !!! We will see to use! Maybe they will get better after several full charges and discharges ??? In any case, it seems to have the same capabilities as the original.
