I did the same with my 20th Anniversary Mac, but only because the
replacement Lithium battery was too expensive to get. I replaced it
with two Lithium AA batteries in a AA holder + wires. :-)

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.
