For some reason, Pacific Gas and Electric just can't seem to learn how to keep
my power flowing whenever little rain falls or wind blows :-(  So I need to get
a UPS.

What rated capacity is recommended for a NeXT Cube with an external floppy and
CD-ROM drive and a modem (I think I'd need to keep all of these running during
a power failure).  NeXTanswers reports that an idling Cube draws less than 150
watts of power (maybe around 115 W., but I can't recall for sure).  My
peripherals are low-power devices, so I would think that my VA load would be no
more than 300 (I think volt-amps = 1.4 * watts).  I don't want to buy a bigger
UPS than I really need, although I guess I could run longer on a larger UPS.

I'd also like to get a UPS with maintainable batteries (apparently the sealed
maintenance-free batteries supplied with many UPS's eventually fail because
they dry out, so the ability to add water periodically could extend battery
life by a factor of 2 - 4).

Any guidance, words of wisdom, suggestions, etc. would be appreciated.  I will
summarize to the net.
