The battery in my camera could no longer charge and was swollen, as it turned out. So I needed a new one. The original battery SAMSUNG is not cheap, but good. Immediately after the delivery 4 weeks before I inserted the battery and load. Photographed since about 50 images and the state of charge is still displayed in full. Original products are relatively expensive, but with imitation products I have had bad experiences. They are then more expensive in the end.
