As a follow-up/closing comment to this discussion, after contacting ACR regarding battery replacement, I discovered that our PLB 100 is now considered "obsolete" and they will not replace the battery. As an alternative, however, ACR did offer an exchange for a new "TerraFix" unit for less than the cost of a replacement battery for the PLB 100. The TerraFix is also a "discontinued" model but will be serviced for some years to come, certainly as long as the life of a replacement battery for our old unit so I could do worse.
On a positive note, I learned that the cost for the batteries for our GlobalFx has come down by about 25% since our last replacement so I'm ahead there although there is a good likelihood that this unit too will not be "rechargeable" after this cycle.
Considering the foregoing, and my experience with Garmin as to its Chart Plotter/GPS devices of late, it seems that the life-span of electronic devices is about 8-10 years and cost/benefit evaluations should be made with that in mind.
