I have done this on a 48T02 for my SPARC2. I did it at one end of the
chip and I cut *through* the leads going up to the battery to disconnect
it from the SRAM entirely. After I exposed the leads, I soldered on a
9V battery cable which I snapped onto a 9V battery top (removed from a
dead battery), into which I soldered a 3V lithium battery that had solder
leads already bonded to it (scavenged from a dead board of some kind).
I placed all the active bits in a small ziploc baggie for insulation and
closed up the case. I do have a replacement 48T02 on order ($15 from Mouser),
but for now, I'm running.
