And yet another, another weird corrosion story (not synth related)

[Hairy Harry]

Possible but not likely.

Probable is that when the battery acid leaked, it corroded the
battery and flashlight shell and made a conductive path
shorting out the batteries, and the discharge current made them
warm.

If the shell of the flashlight was plastic, then same thing, but
all conductive material must come out of the battery...

This is real intersting stuff. I do a lot of "forensic science"
for a living. Like "What killed my machine and how can I make that
never happen again". But these usually get much more than "warm"...
