Maybe it will run out of power, or maybe Voyager save won't connect? All seems good so far, Keyboard issues are gone and it runs well. I'm about 3 months into a new set of fresh high-quality batteries. Since I'm currently fully backed-up, and there's some free time, I think I'll test again to check the Voyagersave operation and see how the voltages are looking.

...So I did the checks, after 3 months of daily intermittent use, 5 days a week. Batteries were draining evenly, currently at 3.03V each. My added wire to fix the connection between the negative terminals has a small bare patch, so I can measure battery voltage from there to the top exposed positive faces, without removing a battery.

And I did another Save file which connected and saved fine. I imported it into Pierre's (awesomely useful) Excel file to save and check my listing's.

BTW I've got a small but eclectic program collection for the '15c now. I'm a structural engineer with an outside interest in electronics. So I have a program for structural section properties of box sections I sections and circular sections, one to assess reactances vs frequencies of capacitors and inductors, and a Celsius to Fahrenheit converter for helping with some US-based fire temperature calcs.
