In order to assess the battery is 100%, I have to use it for several months. Battery is not the same battery even when it comes from the same company and the same name has. Who can say how long the battery has been located in the store, what temperatures he was exposed to during transportation, as it was stored me etc.
Supplement 03.26.13 ... unfortunately has been found that the battery is not that brings what it promises. At the moment I put one and after about the fully charged battery, 20-30 images shows the battery status indicator turns red. The second battery behaves like that. Poor quality!
