I'm confident that I could find the whole thing.  How useful that would
be is a different matter.  :-}

I suspect that a couple of salient criteria would be the capacity/size
of the UPS & what kinds of batteries it uses.

The UPSen I use at home use 12V, 5.0 Ah motorcycle (lead-acid)
batteries, which are pretty generic.  The UPS for the MUX for the
DS3 that's being installed at work uses Li-ion batteries; I suspect
that they are rather less generic.  :-}

You've tried various resellers?

Anyway -- I ended up buying the 12V motorcycle batteries from a
place in San Diego (Rage Batteries).  Granted, that doesn't qualify
as "local" for this context from my perspective, but the price
(including shipping) was better than other sources I found, and I
was able to buy 15 of the batteries without being concerned that I
wouldn't be able to actually receive all 15.  And they've been
working fine; that UPS keeps things going for about 1.5 hours now.

IIRC, the batteries were made by Yuasa.

Peace,
