I'm not sure, I don't personally see it as something worthwhile to
investigate when you can just rebuild the old NVRAMs. Even if you do use a
SNAPHAT type replacement, you're still stuck with proprietary batteries
that will one day no longer be made, versus an extremely common CR1225
cell. I've made total replacements for NVRAMs that are not easily rebuilt,
such as the Dallas DS1244:

But, that's a lot more effort and expense than just sawing the top off a
dead 48T02, gluing on one of my repair boards, and soldering the leads :P
