Which is why LiIon cells are *so* hard to come by in the raw.

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.
