I've been able to monitor:

1.3.6.1.4.1.476.1.1.1.1.13.4.1.2.1
1.3.6.1.4.1.476.1.1.1.1.2.3.0
1.3.6.1.4.1.476.1.1.1.1.2.1.0

The first(...13.4.1.2.1) is almost assuredly AC line voltage - set up MRTG
with a test UPS and pull the plug, and it goes from 0 to 120, plug it in
and it steps right back to 120.

The second and third have been more difficult to figure out - I'm a
little hesitant to test one of these things in production. I think
that the second (...2.3.0) is DC voltage across the battery terminals
(and thus the fully-charged value will vary among Liebert models),
while the third (...2.1.0) may be something along the lines of
"projected battery lifetime under current load".

Caveat: neither of my testbed Lieberts happent o be 300's.
