APC UPS Battery Backup & Surge Protector, 600VA Backup Battery Power Supply, BE600M1 Back-UPS with USB Charger Port

Easily connect the red wire to the battery after unpacking because its not connected during shipment; charged it for 24 hours snd then connected my cable modem and router each to a surge/bavckup port and today tested by unplugging the ups for 15 minutes and it switched to battery backup so fast my network had no clue it seitched and all my network devices stayed connected like normal. So after 15 minutes i plugged the ups back in ad it switched back to power seamless-sly.z. Very nic e product. I didn’t bother yo connect yhe usb cable to my computer, but I’m sure the ups management would work fine. Very nice product. Battery would be easy to replace if and when that would be needed. Great product !!!

I got this to provide power to a PC and Playstation during power outages and so far it has worked like try champ. It was really easy to set up and makes absolutely zero noise (it sits under my desk). As with all backup batteries, longevity can be subjective. I've has UPS devices that have lasted for a decade, then I've had others that barely made it two years. Time will tell with this unit. But for immediate use it seems to be doing the job as well as can be expected.

My electricity was blinking off on a regular basis, just for a second but enough to reset my computer and gateway/modem. Since putting this baby in between the outlet and the cords for all my electronics, have had zero problems. Some of the better money I've ever spent on electronic gear.

Not sure if the reviews are lumped together so just to specify, this is for the BE-550G. I have historically never bothered to run a UPS, but I've been having minor power flickers in my house lately, a couple times a week that would reset my computer much to my annoyance (I run my desktop 24/7). I thought I should get a slightly bigger UPS since I have a custom built budget gaming rig, but I did some quick finger math and decided this one would work "for now". The device came with about a 95% charge if I remember correctly. I plugged in my computer and one monitor to the battery side and let it charge up to 100%, then gave it an extra hour or so. It claimed something like 150 minutes of runtime in the APC monitor program so I decided it needed a calibration. I set it all up for a worst case scenario simulation -- I used MSI Kombustor to load up the CPU and GPU and then pulled the plug. I wasn't 100% sure I'd picked one with enough wattage but it didn't flinch. It did however tell me I had 1 minute before shutdown (set to shutdown when 5 minutes remained). So I quickly set the computer back to idle and the runtime jumped back up to 7 minutes. I let it run to shutdown and everything worked just as it should. However one of the safety features caught me off guard. Forgive me for not looking up the specifics right now, but basically wait a couple minutes after power is restored if you drain the unit until it shuts down. If my memory serves, the safety feature will shut down the battery for 2 minutes (or maybe one?) after power is restored after a full drain then cycle the power. So being "that guy" who doesn't like to read directions, when it died I plugged it back up and hit the power button on my computer... It booted most of the way up then there was some beeping (from the UPS) as it cycled the power and my computer reset, and about the time it got back to the BIOS screen it cycled the power again with some more beeping. The more you know. It can't possibly be good to fully discharge a battery in 7 minutes or less, but this thing functioned flawlessly and could be a life saver. It didn't even heat up that I could tell. After my "calibration", the monitor program now says I should have 15 minutes at idle, which is probably pretty close to accurate and more than I should ever need. The next day after I hooked it up the power dropped out for a couple seconds during a storm, the UPS kicked on just like it should, and reported the problem to me in the monitor program. Now I'm just wondering why I didn't buy one of these sooner! Note that this thing takes forever to charge itself (think 12+ hours from 20% which was the magical 5 minute cut off on my system), probably to avoid unnecessary lead-acid battery related risks on your carpeted floor, but that shouldn't be an issue unless you're having constant power problems. Just a note for anyone who (like me) sat around scratching their heads about which UPS will do what you need, maybe this will help... I already told you the estimated runtimes I got, here's a rundown of the power consumers on my rig: CPU - AMD FX-4350 @ 4.2ghz GPU - MSI NVIDIA GTX-760 Gaming Storage - 2x WD Red HDDs, 1x Samsung 840 EVO SSD Monitor - Asus 23.5" 1080p Update 10/16/2016: This unit is still doing its job without a complaint. The PowerChute program tells me that the unit has switched on twice for "blackouts" totaling 9 seconds and twice for "electrical noise" totaling 24 seconds, in the past 24 weeks. It doesn't seem to register extremely short-lived problems (a second or so), I say that because on a couple occasions I've seen the house lights flicker and heard the unit rapidly click on and off with no report. No big deal. Also the Estimated Battery Time has gone back up to 145 minutes, I haven't bothered to recalibrate because I never really look at it anyway and I know what it'll do. It periodically reports that it passed a self test, which is nice although I'm not exactly sure how it performs that test.

Pros: Easy to replace battery USB monitoring USB charging port that works off battery or utility power Wall-mountable (though screw keyholes are 213 mm or 8.39" apart, not sure where they got this odd dimension) Entry-level cost Cons: No LCD display No mute button I'm not crazy about this form factor Battery is expensive I have two of these. They don't have huge capacity so they won't run anything with a lot of power draw for very long, but if you want surge protection and a computer or other device to not instant-off with a 2-second interruption in power, these work great. There is an easy-to-access, toolless battery compartment though a replacement battery is more than half the cost of the unit, which is not typical. It has a USB-A charging port and a USB-B port to plug into a computer (it comes with a cable) to monitor the power status. I'm not crazy about this form factor and it doesn't have an LCD screen or mute button (it only has one button) so you have to refer to the manual for the color and blink pattern to determine what it's telling you and will need monitoring software to know what the load and available battery power are. It's a good entry-level UPS.

Purchased this to keep my desktop computer operating during a power outage until I can save my work and do a normal shut down. I haven't had a full power outage yet, but since installing, the power went off and on three times within 15 seconds. This backup kept the computer and monitor on without any problems. It was easy to set up and a small size under the computer desk. I can't comment on and haven't tested total run time, which wasn't my intended purpose, nor can I comment on its longevity with using it for a month. Update: I've had this for 3 months now and it has saved my desktop computer with power outages 4 times. I still don't know its run time, just desktop and monitor, but have had time to do a normal shutdown with the longest being 10 minutes. I hope it lasts a long time and will buy another when needed.

I have purchased 3 of these so far and they work well and seem to be very good quality

This APC backup battery has been extremely useful, not only for protecting my electronics but also for identifying a problem I did not realize I had. It kept clicking on and off, which at first I thought was a defect, but it turned out to be a voltage issue in the wall outlet. Once I fixed that, the UPS has worked flawlessly. The unit is compact, easy to set up, and provides peace of mind by keeping my computer and equipment protected during power dips and outages. It also gives enough time to safely shut things down if the power goes out completely. The build quality feels solid, and the indicator lights make it easy to monitor its status at a glance. I have tested it during short outages, and it switches over instantly without any interruption. It runs quietly, and the included outlets are spaced well for larger plugs. Overall, it is a reliable and well-built UPS that not only protects devices but can even help you spot electrical issues before they become bigger problems.
