I have over Easter under different climatic conditions (cold: in the mountains of Switzerland; Tropical: alone 2 hours in Masoala House (rainforest) in Zurich) made about 750 pictures and with frequent reciprocating zooming and showed the battery still 2 dashes! However, I must emphasize here that I fotographiere only through the viewfinder.
For me enthusiastic globetrotter a powerful, reliable battery is essential!
For the Nikon-original battery I forgive convinced 5 STARS!
