I'm replacing a small button battery (CR 2032) with two AAA batteries, I'm

Is the heat that I would need to apply to the button battery with the
soldering iron to solder to it, likely to make the battery prone to
'leakage' in the future? Or perhaps cause it to go bang at the time of
soldering? Thanks for advice.

There are warnings about charging lithiums and having them explode. I
have never heard of it happening #
Oh I have. Lots :-)


and have seen applications where they
were being charged and nothing happened. (they must be very toxic-you
need a label when shipping them)

They are not toxic, but they can pop nicely and start decent fires when
shorted.
