So you're suggesting that I can restore the batteries by chewing on them? :-) This thread has gone waaaayyyy off track. How about a PIC solution? What I need first is some theory on an electrical way to recondition the batteries, and I can build a device around that. I'm still sticking with reconditioning as a solution since my experiment with manual cycling produced good results for me. BTW, why does a C-section lead to "hence" your attendance? Are you a photographer, c-section medical professional, or a c-section enthusiast?

Had his camera ready to take the obligatory photos and guess what.... no juice left in the dry cell for the flash/winder. We tried warming the cell, all to no avail. In the end the husband bit it really hard until it was almost crushed... put it back in the camera and voila... got 8 pictures (with flash) before it died again. Something about cells being crushed together....... Saved his bacon for certain! One of those things to keep in the back of my mind (just incase!!!)
