UPDATE: I got feedback from David KM4UHS that the original FBA-23 steps up voltage to 4.5V (unlike knockoffs that do not have the step-up circuitry).

Yes, I do recall that the radio reads out 4.5V whenever I used the battery case. I wonder what happens when one uses Li-Ion 14550 cells, though.

I have since let go of the radio, so I have no way of knowing now.
