Haven't had the chance to test exactly how long it lasts, but so far hindi pa naman nauubusan even for hour-long outages. I added my PC to it and run extensions going to the fiber ONU and access points.
It's super heavy, I think it has six of the 12V 9Ah battery modules you typically see in a 500VA UPS.

IIRC UPS usually provide 5 mins backup time at their rated load, so backup times should be something like:

2500W - 5 mins [max load]
200W - 62 mins (1h:02m) [moderate load i.e. light gaming including PC]
95W - 131 mins (2h:11m) [light load i.e. browsing including PC]
60W - 208 mins (3h:28m) [monitor off, PC almost idle just to run background tasks]
15W - 833 mins (13h:53m) [modem and access points only]

In practice the fiber modem by itself uses 7W or less. I saw a youtube video where a guy ran the modem for over 24 hours using a 40Ah car battery. He monitored actual energy use and it only drew 0.6A at 12V, consuming about 15Ah total over 24 hours so his 40Ah car battery will weather even a 48 hour blackout.
