I took some standard nimhs (Lenmar Nomem 200mah) out of my charger, my brother put them in his camera, and the camera immediately reported the batteries were too low to run the camera. Then I gave my brother my hybrid nimhs (Uniross Hybrio) from my cordless mouse - he took 152 pictures on them with flash, and the camera still reported the battery fully charged. I took back the hybrid nimh batteries and tested them to see their charge level - they had less charge than the batteries that the camera rejected immediately! What is the explanation for this?
