APC 750VA/410W Backup Battery Power Supply for Home Office, BVK750M2

Purchased this device to stop having to re-start computer system whenever power flickers. In new area, power supply is not stable, lot's of lightning and 1-2 second power loss. This keeps my computers going, especially with docking station. I have not used Tech Support, so no rating. Relatively inexpensive.

No more restarts created my very shot term power outages from strong spring thunder storms. I just keep on working.

So I've owned this for about a year. My NAS is plugged into it and my NAS monitors the UPS via USB. My only issue with it was that I kept getting battery errors telling me that my NAS was getting ready to shut down (it didn't) and then another message that the battery needed to be replaced. Well I finally replaced the battery 06/26 with an Energizer 9AH AGM battery and the errors have gone away. Battery took me about 15 minutes to replace. The battery that the unit came with was not the APC branded battery that Schneider Electric tells you to use but a cheap generic battery instead. So I take away one star for the battery it came with.

It's not a ups. Had this for my computer and it turned off everytime before the battery could take over. Also peeps and I'm not exadurating it beeps like a fire alarm lvl of loud. Very much not worth it and died after 6 months

Have had this unit working 24/7 for over a year. We live in the country and have fairly regular power outages. This unit has worked flawlessly during each outage.

Today: 10/22/25 It was almost exactly 3 years ago (Oct 11, 2022) that I bought the BVK750M2 unit. On 10/19/25, the unit started blinking all its LEDs, and turned on a continuous alarm. I took it out of service, expecting to next open it up and replace the SLA Battery inside it. Today, I attempted to do so. After initial inspection, I guessed that the battery would be accessible from the front. I will add that I could find absolutely NO video online to do this replacement. After I took out the screw, I could not budge the front panel cover off. I notice a couple of tabs, but they did not seem to budge much. I called tech support after searching the Schneider Electric site. They answered! Took my information, including buy date. CSR went off the air for several minutes and came back and told me that battery was not field replaceable and I had to contact Coastec.com, an east coast company that empties its offices at 5pm ET. I then asked the CSR for a number to call to lodge a complaint with SE/APC. (I fully expected to replace the battery myself). Next, I called that number, which also went through the same IVR menu, and landed me with another CSR. They took my info, and went off to consult about my product. Fortunately, they referenced the previous call case number and were up to speed. They, too, came back and said the same thing (not field replaceable), but said that the product had a 3-year warranty, and I was really close (just outside) on that warranty. They went to bat to supply me a replacement unit. Make story short, I was very happy with this turn of events. I had paid $109 in 10/22, and it's now $149. It had a 3 yr warranty, it's now 2 yrs. Battery was considered field replaceable and is now NOT. Even to this day their literature says field replaceable. HOWEVER, NO DOCUMENTATION exists to actually replace it! Anyway, here's how I'd rate the product: 2 stars, but 1 star for support. Would I buy again: NO. Not field replaceable is worthless. No UPS I've ever personally had (10s) came with this limitation. So, buyer beware of this model.

And a power spike did it in. Should have had one of these like I did on my other PCs that had no issues

May 2024: I bought two of these and noticed substantial off-gassing or possibly battery odor at first, and almost returned them, but it subsided within a few weeks. It is my understanding that the country of origin of the battery might be implicated here (when it's India?) but I haven't needed to research that further yet, but follow up with that possibility if you have similar concerns; apparently it is a bit of a known issue. They don't stink now, though. But you might need to let them air out before putting them in a space you'll be in regularly if it bothers you. I'll update this if that issue returns or something else happens. November 2024: These eventually stopped off-gassing after two or three months and have worked flawlessly with a number of issues with power instability including recent storms this month that caused a lot of brief power sags.

Good quality! Serves its purpose. Worked so well, I bought 2.

It works out of the box. Takes a while for the battery to fully charge. The led light is quite bright and can't be regulated by pressing the power button although the documentation says it can. The power cord has a standard 3 prong AC plug. Other APC ups' have a flatter plug with an angled cable design that is easier to use in tight spaces. It has a battery disconnect link that allows you to disconnect the battery for shipping or when you open the case to replace the battery. The unit is shipped with it disconnected. APC says the battery is not user replaceable but it can be by removing 4 screws from the bottom of the case and then separating the top and bottom. There are videos online that illustrate is procedure. The least likable feature of the ups is the 4 connectors located on the back end of the unit used to plugin the supported devices. The receptacles are placed directly adjacent to each other so no wall warts or other nonstandard plugs can be used if it covers more than a single receptacale can be attached, only the standard 3 prong AC plugs. The ups is certainly large enough to accommodate more space in between them. I use the apc powerchute software from the manufacturer. This allows you to see when the unit was manufactured so you know how old the newly suppled battery. Be sure to register the product!! It is interesting that even though the unit is constantly plugged into the wall and under a less than 30% load the the battery charge level drops below 100% without an AC power loss and then charges backup to 100%..

Bought this for my PC, it has a Ryzen 9 7900x and an Nvidia 4080. This is enough power to allow for the pc to be shutdown properly in the event of a power outage. What its really great for is "cleaning" the power that comes into the PC. I'm in an old building with old wiring in a city, the power moves around a bit, every couple of days I'll hear the UPS click off and on, especially in the summer when all the AC's are going. That's not good for the PC so the UPS really helps in that regard as well. Simple setup, wish the cord was a bit longer but that's pretty much my only issues with it. You can get the personal version of the Powechute software to configure it off their website.

If you need a loud beeeeeeep, that continuously cycles, this is the device for you! As for supplying power not so much. Died after 1 month of use.

I've had my APC UPS 750VA for approximately 3 months. I've had several overnight power blips and noticed that my desktop was shut down, the following morning. I should have downloaded and read the full manual because it seems the unit only receives configuration from PowerChute software, not the Windows power management configuration as my previous UPS units all have. In addition the battery is "not user replaceable"?! That's a first for me. And, to top it off, I just had a 5 minute power outage and the unit died immediately, and will not restart. The last time I checked PowerChute, this morning before the outage, the unit was running at something like 22% capacity and had an estimated 24 minutes of battery power. At this point I do NOT recommend.
