One of the two accus supplied defective. He was (inflated approx 0.7mm) at the center of much thicker than the edge and could not be stuck in the Accu bay. Fortunately, the Accu was broken already in the supply and has become not only defective in the camera. Then he would have been no longer figure out and had a probably costly repairs pulled up. Can not therefore recommend the Accu. Everything returned and completed experiment.
