What do you want to tell your friends an original battery? A second battery is a must for the lack of performance of the camera image. Because it makes Casio better. We photographing a lot and the Casio battery has at least six months held with flash and zoom. In Fuji I have a manual zoom and the battery lasts for about 200 photos. But as the camera takes very nice pictures, I needed a second battery. Unfortunately, you can not upload internally in the camera's battery. For the camera must always be unpacked and separated with difficulty.
