I did this on my old T23.  Take the (regular) battery out, and you should
see the CMOS battery wrapped in yellow plastic with the IBM part numbers
stamped on it.  The IBM part is {battery + plastic wrap + wires +
connector} and pretty easy to install--no soldering--although the geometry
is a little tight.  The part seems rather expensive but I ordered it right
from IBM (here in the USA).

As the other respondents said, you can consult the Hardware Maintenance
Manual; it told me how to do the replacement.
