However, simply not true the statement "For Coolpix P7700 (incl. Update 1.3)", the camera (Coolpix P7700, Firmware Version 1.3) can be with this battery does not turn on. Since Firmware Update 1.3 has not really brought significant changes to the version 1.2 (probably were Nikon only Fremakkus locked out with this update, and the whole covered with forwardmost give reasons), you can from version 1.3 to version 1.2 downgrade (Easy Firmware Update 1.2 as a firmware update on a camera play with firmware 1.3) and then the battery is working properly.
