I have found some presentations on YouTube about reconditioning old laptop batteries by putting them into a freezer for 14 or 15 hours inside a plastic bag, removing to room temperature for temperature to return to normal ambient, and then fully charging and draining a couple of times, and this is supposed to bring a dead or dying battery back to life. Does this really work? How long does this effect last, if it is true? What is happening physically or chemically in the battery by this freezing treatment?

No clue if it does or not, the best way to find out I would imagine would be to try it. . .the thing is most bad laptop batteries are only defective because people keep them constantly charged and they develop a "memory" so to speak. If you can find a way of erasing that memory, it would fix the battery. Of course, its good to completly drain your laptop battery every so often, say once a week (I mean dran, all the way to shutoff) and then recharge it, to help keep the battery from getting that way.
