Thanks for your prompt and continued help!
The second preference listing was adjacent to the first, if that's what you asked about ("... the second one?".
Emptying the trash and starting over twice didn't help... still running after two minutes with the pref is set to shut down after one. Same story with the other two optional methods (minutes remaining and % of capacity) .
That's quite strange. It's a very long shot, but try a different USB port and cable (and combination of the two) anyway.
As I understand it, OSX periodically interrogates the UPS, both to make sure it's still there, and asking for the % of battery power.
When utility power is interrupted, and the UPS switches to battery power, it sends a signal to OSX. I don't think that signal is in response to the request from OSX, so apparently there's either a hardware problem preventing the signal from getting to your Mac, or OSX isn't dealing with it properly.
If different ports/cables don't help, something may be corrupted in your installation of OSX. I'd suggest downloading and installing the "combo" update. That's the cleverly-named combination of all the updates to Snow Leopard since it was first released, so installing it should fix anything that's gone wrong since then, such as with one of the normal "point" updates. Info and download available for 10.6.4 at:
http://support.apple.com/kb/DL1048 or, for 10.6.3:
http://support.apple.com/kb/DL1017 if that's what you're on. Be sure to do a +Repair Permissions+ via Disk Utility (in your Applications/Utilities folder) afterwards.
But don't delete the download unless it fixes the problem. If it doesn't, reinstall OSX from your Snow Leopard Install disc (that won't disturb anything else). Then re-load the "combo" again.
