I would run tcpdump and record and examine the SNMP traffic, and turn on
debugging in the driver.  It is likely that the SNMP queries for status
are not doing what the driver author expected.  You'll have to find out
if your UPS has different variables.  snmpwalk may also be useful, or
docs.

Also, which version of NUT is involved? There were recently PRs (merged to
master-branch, eventually will be in 2.8.1) about more SNMP-UPS support
including APCs e.g. 1674, 1679, 1113 (should be in 2.8.0)...

Many distros still ship 2.7.4...
