Different topic and worth discussion.

I attack it from a different view.  I assume batteries will
discharge when least desired in storage and will leak.

All my PCs that have CMOS batteries accessable have a external
(.6x2x1.5 inches) plastic box with a suitable battery placed
in it and wires to the internal battery location.  I had a 
bad experience early on with NiCd leakage on a board so off
the board they go.  External makes for accessability without
opening the cases.  It also allows me to use a battery that
is larger or better that would not fit where the orginal was.
I apply this to a my otehr systems as well, S100 toy clock 
battery, MicrovaxII TOY clock battery and similar.

I agree heat and batteries generally do not get along well
and storing equipment with batteries installed is also risky.
