Many years ago, a "Good Old Boy" from Georgia showed me how to
resuscitate a battery that was shorted: he drained the acid into a
bucket, filled the battery full of water, turned it upside down and
shook it as if he was making a cocktail for James Bond ("shaken, not
stirred..."), then drained it out (note that this *does* require some
muscle.) After doing that several times, he refilled it with acid, and -
presto - working battery. I've used that trick with shorted batteries
several times in the years since, and have been successful every time -
which, I suppose, supports Arild's point.
