About Liebert PST5 UPS - 500VA/300W 120V, Standby Power, 8 Outlets
Overall Feedback:
73% positive
73% liked the battery life, but 27% found it didn't last
For brief power outages that rarely last more than a few minutes, the battery life is sufficient.
During testing, my battery level indicator dropped below 25% after 50 minutes of usage, but it was still running.
The battery life is not good and it lasts for about 20 minutes while powering only the modem.
After the first brief power outage, the unit went into replace battery mode, indicating that the battery would not hold a charge.

66% appreciated the control features, while 34% found them confusing
I found the unit's feature of monitoring incoming current and automatically switching my PC to battery in case of power loss to be useful.
I bought the unit to monitor key information, but I cannot access it on my Mac and I do not want to crawl on my knees to see the LCD screen.
The apupsd driver shows some information, but there is a communication error and no control.
76% praised the high power capacity, while 24% found it insufficient
The UPS kept our cash registers, internet, and phone lines running perfectly until the generator could take over.
Instead of muting the UPS speaker, I suggest getting a more powerful model that never reaches 100% capacity to avoid beeps.
74% found it whisper-quiet, while 26% thought it was loud
After holding the button for 2 seconds and releasing it, the UPS became whisper-quiet.
During full-on power outage, the unit beeps every 10 seconds loudly and cannot be turned off.
If I get a more powerful model, I will not hear a single beep.
