My experiences with the APC Smart UPS series under Windows NT was that
when the battery began to run down (I had left it unplugged one day),
and reached a critical level, the most awful sounding alarm began
beeping until the system recharged itself. After it recharged itself,
the alarm stopped. It never reached a level that the computer was shut
down but UPS said that when the battery level was too low, it would
automatically initiate the shutdown sequence.
I would assume that the same thing would happen under Linux.
Be also aware, that like all rechargable batteries, there is a certain
life span to them, and that they are expensive to replace. I think I got
about three years out of my first battery.
