The places I've been who supply large numbers of replacement batteries
all have a fancy welding rig which they can use to stick a set of bands
on any battery, including lithium, by welding. Then solder to that. It
may not be as pretty as some of the soldered approaches, but i agree
with you, I'm not going to apply solder heat to a lithium battery. It's
all about heat not temperature to make them explode.
If you're lucky they will have them as Ethan mentions below already in
stock.
In my case I was going to fix a rechargable razor, and they even said
they would do that for free, make up the pack and put it in the unit,
they do those all the time. Doubt they get many sparcbooks though, I'd
probably do that myself.
First google result for "Sun NVRAM battery
replacement":

Ooh... I've seen that page before, and that technique looks dangerous
(the soldering to the Li battery part).
I've replaced batteries on "Timekeepers"
before, but I either use the
batteries that have solder tabs pre-welded onto them, or use a snap-in
battery carrier and solder the leads from that to the chip.
