I was told by one of the big battery manufacturers engineers that there is
absolutely nothing wrong with paralleling coin cells anyway, as long as you
don't parallel above 10 or so. Not sure about others. Above that, an
internal safety mechanism (in case of shorting) would no longer be
effective, and could be dangerous. There were also no issues with one
discharging the other.
Someone else might have a different answer of course.
