camera battery life
Up to now I have been using Nikon EN-EL15 batteries which are ok but now loosing some of their life span. There is now the Nikon EN-EL15a battey available for my camera, even that is out of date with a new "b" version.
I recently purchased one EN-EL15a off ebay at about £20 cheaper than UK prices. Yes I know about the risks but boy did I do well.
I have been trying to see how many photos I can get on one charge, so shooting like mad and still got 79% battery life left from well over 100 pictures taken.
By this time my older batteries would be visiting the charger for a top up.
