    You can use the app to set parameters.

    I own several of these some a old as 14 years. They are very durable the only maintenance required is to change the battery every three to five years. I love the ability to be able to program them with the app. I can even program them to turn on if even for a moment if there is to much distortion on the power coming from the power distribution company. There are other parameters that can be set some are similar to those offered by other manufacturers, the difference is APC backups can be set to tighter tolerances. I have a standby generator so when the power fails I know I don't have to worry

    Excellent UPS

    I really REALLY like this unit. I previously had the other big brand and didn't like it much. It was constantly beeping in the middle of the night, which never made sense to me - why do I need to be woken up at 3 a.m. to be told the power's out, just do your damn job, UPS, and keep the power going if something's plugged in! This one has downloadable software that let's you choose your settings, one of which is to turn off those stupid f'ing beeps. Moving along ... I just pulled the power cord out of the wall to see how long the battery would last. I've got a PC (with a mobile CPU), monitor, mi

    Two consecutive storms for my new UPS

    I installed this UPS and ironically the following two days we had terrible electric storms and power went out these two consecutives days, the UPS kicked in without a glitch both times. I am using it it mostly to protect and keep my fiber modem running as well as my computer switch, so my internet stays up during these electric storms. On the second day the power was out for almost one hour and the UPS battery was still delivering power to these two devices, so I really was glad that I had a real life scenario to test it.

    It has worked several times. One problem is the supposed download to allow it to restart. It does not work in fact after download zip files do not actually appear. Could be my inability or it does not function properly. Downloaded several times same problem. Tried to report to the company, no response.At least it does protect the files.

    So, You Think You Don't Need One?

    Where I live, power outages are a regular thing, especially during high temperature power drains in summer or A-N-Y type of other weather extreme.Just purchased an APC® Model BE650G1 after a catastrophe. In the past, I was too cheap to buy this level of protection, and frankly, thought I didn't need it.Anyway, this unit will be in my home office FOR AS LONG AS I AM ALIVE, connecting a: 1) BRAND NEW Windows 11 Pro PC desktop [tower] computer, 2) a 32" LCD monitor, 3) a fiber-optic modem, and 4) a DECO® "mesh" router, to the "BATTERY BACKUP/SURGE PROTECTION" side ... and a network "Hub", a TABLO

    Mine lasted 11 years until I did something dumb today

    Love it and immediately reordered. Had some water dump directly onto the unit today...had some green onions in a tiny cup of water in the window directly above it. What are the odds. It made the most INTERESTING sound!Panic ensued until I realized I could get a new one in the next few hours.11 years and I replaced the battery only last year. So I highly recommend it.
