According to the website you mentioned before, the UPS supports the things
that are typically found on UPS'es that have a contact closure interface.
In almost all cases, this means that indeed the UPS has a contact closure
interface and that these values can't be read from the UPS.

Note that the fact that a UPS driver is able to read these values from one
UPS, doesn't mean that it will also do so for a different model that
happens to use the same driver. NUT also has drivers that support very
different UPS'es with a single driver and that auto-detects which is

The fact that the first one is already broken speaks volumes for what you
can expect inside it.
