Have the Original Battery EN-EL5 with my P6000 since 2009 in use, because the original included with the purchase of the camera. The battery was from the beginning scrap because he has discharged the case even after 3 days. Even if the battery is fully charged away from the housing and sets aside, he was completely discharged after 1 week. I've googled for a solution of the problem in 2009 and took over a test report on the P6000 at Chip.de out that you already familiar with the problem and, unfortunately, can not do anything. Was with Nikon from the outset an aberration in combination with the P6000. So is not only the battery but also the housing that the battery constantly takes juice even when switched off. With the high price of the camera and battery very annoying.
