Query: Battery life

If you are looking for the best battery for your Nikon don't think about it spend a few bucks more and buy the original one. it has the best life time than ever one, and kept charger on your bag for a longer bit. this is my second battery and splitting with the one on my camera improve my time for pictures.Having 2 batteries avoid me to miss something really cool I could leave one charging at hotel or have both with me complete full for a long photo session.
