(Googles, to look at a picture)

I'd order the proper battery, but to tide you over till it shows up,
just cut apart the shrink wrap on the old one, and cut the wires as
close as you can to the tabs, or actually cut the ears off the tabs. You
want bare metal showing on the end of each wire. As best you can, tape
them to the new cell from your fridge, making sure to keep polarity
correct. Gently put it all back together, and try not to bang things
around till the new battery shows up. This is not a high-current
application, so as long as it is good metal-to-metal contact, and
nothing shorts out, it should work.

Of course, all this only works if you have enough slack in the leads,
otherwise you would need to extend them.

I have done home-brew laptop CMOS batteries like that more than once.
Some ended up being permanent fixes, since the correct part was not
available, or cost more than entire laptop was worth.
