I changed the cap this morning to the "ultracap". It went the same as other supercap remove/replace instances.
The caps arrived with about 3.2V charge (all 5 caps). They say not to let the leads short, so I was careful of that. The precharge is similar to the lithium CR123A when it is fully charged.
The station is reporting data again and is working. Hopefully, the charging/discharge will be OK. I suspect that I'll see a longer run time on the cap since it is 30F and the original is 10F.
It was an unremarkable, routine exercise. If anything unusual develops, I'll post it here.
