Recently I wanted to replace the tired battery pack in my old Sony PC7 camcorder. The problem was that it is an obscure battery these days. My solution was to buy a commodity camcorder battery (Polaroid branded), ignore the "do not open" warnings, and substitute the working innards for the tired ones in the casing that fits my camera. I do *not* recommend doing this yourself. It was key that the batteries (and in this case charging electronics attached to them) matched between the two camera designs. Had I done this wrong I could have burned myself, lost an eye, etc. -kb, the Kent whose camcorder is usable again.
