Got the NiCad Blues?
Hasselconverter replaces the troublesome original Ni-Cad batteries with an easy to find, cheap 9 volt battery. No modifications to the camera body required. Simply install and kiss all those frustrating battery problems good by! Comes ready to go with batteries. I have sold several thousand of these to camera repair shops and photographers since about 2000.
Added benefits: Camera winds faster and you get about 1200 exposures on a set of batteries. You simply will be amazed at how well your camera will perform with these adapters.
