I have the battery properly now for almost 3 months and it works! Where the original battery with 860mAh 6.36Wh is because this has 950mAh 7Wh! This is not much more, but it makes itself noticeable in use and that is what counts. Despite Accessories of battery as the original fits into the camera and charger.
So if / second battery is looking for a cheap replacement, makes nothing wrong!
