APC UPS Back-UPS Pro 1500VA UPS, 900W Battery Backup & Surge Protector, AVR, 10 Outlets (NEMA 5-15R), LCD, BX1500M Uninterruptible Power Supply for Computers, Wi-Fi Routers, Home Office Electronics

Overall good UPS. I have purchased several of the same models. I use them for my computers and also my home theater system (amp, TV, PS5, subwoofer), and other electronics. However, all my APC units have the same defect in the self-testing mode or during a power outage at the house. Although, the defect during self-test is infrequent. Sometimes during self-test, unexpectedly the unit's alarm starts making a racket. I look at the display panel icon which indicates the battery is completely depleted. The first time this happened, I turned off everything connected to the UPS because I thought it would suddenly cut the power to them because the UPS thinks the battery was dead. The same issue could happen if there is a power outage at my house and the UPS switches to the battery power. After, I unplugged the UPS from the wall and cycled the power button off and on, the mysterious "problem" with the "failed" battery was self-corrected. The battery icon then showed it was fully charged: it had gone from full discharge to fully charged in an instant! Now that I know about this defect, when the alarm goes off and the panel indicates the battery is dead: I mute the alarm and leave my equipment on that is connected to the UPS. (There is no a power outage at my house.) It is a false alarm. In about 24 hours, the UPS mysteriously corrects itself and behaves normally. I can disconnect it from the wall socket and my stuff works fine and the battery level shows that it is fully charged but of course starts to show the remaining time left to depletion.

Keeps power to your pc in the time you need it most. It has saved me multiple times when im programming some parts on solidworks. Or when im playing some video games. Im able to save what I got going on, and turn the computer off the correct way before the power just gets ripped right off of it.

I bought 2 of these and 1 I've been using for about a year without any issues. I've had intermittent power outages throughout the year and the UPS has kept my servers online through all of them. The second one I tested but then put into storage. I mistakenly forgot to flip the battery so the battery died. I expected that but before buying a replacement battery I tried powering it on. I don't know if the dead battery blew an internal fuse but shortly after powering on the screen went dark and the unit only passed through power. I tried putting in a known good battery and still the unit didn't function. APC support was very easy to work with and they sent out a replacement unit quickly. Having easy to contact support and no hassle warranty is a huge plus!

My old APC, a ES 750 Backups, was bought in 2008, and the battery on it just failed (yes, it lasted TEN years). That unit was a replacement for an APC I bought at a retail store which was at the end of its warranty, but the battery died. I called APC back then, and they sent me the replacement at the end of the warranty life for free. APC had the best customer service in the business, and despite not calling them this time, I have no reason to think it's changed. I ordered a replacement battery for that 2008 ES750 (I got the Keyko here on Amazon- will see how long it lasts), and it's back in business. If I get another 5 years out of it, one APC purchase will have lasted 20 years and still going. APCs are incredibly reliable, they honor their warranties, and they appear to last forever. Nothing I've seen anywhere says different. I purchased this APC 1500VA because I wanted longer backup battery life, and moved my old APC ES750 to protect my Comcast router. Once a year or so, we have a tropical storm or hurricane that cuts our power for an hour, up to days in a rare hurricane. A 1500 should double the up time of a 750. Also, this has a display that shows the condition of the battery, the amount of power being used, and power load. The old ES750 did not. This unit is amazing. I have a full gaming PC, monitor, sound system, printer, 2 lamps plugged in, and the load bar is barely to 1/3. With the PowerChute software installed (first time I've ever installed it), it says I am drawing 99 watts of power right now (I have printer shut off when not in use). The Estimated battery time is 61 minutes if the power source goes down. There was no discount of any kind available, so before buying I compared every backups before paying the higher price for this APC brand. The difference was a couple of dollars more, but for something that could possibly last 20 years, saving a few dollars was not worth the headache of an unreliable unit or unresponsive customer service. Reviews always make a difference to me in a buying decision, I wanted to address some of the reviews that may have turned me off from choosing this model. 1. The unit makes excessive noise. - I have it positioned under my table, more than 18" away from my actual PC (PC faces my chair, this is turned sideways to face the wall with the connectors facing the PC at a 90 degree angle). The unit is SILENT. It makes NO noise. NO buzz, NO hum that can be heard over my near silent PC fans. I have no idea about the specifics for servers, or how far it should be away from equipment to prevent feedback loop, but for home use, the unit is silent and works flawlessly. 2. The horrible chirping when the battery or AC power dies. I totally relate to this, it's exactly what happened when my old ES 750 went, and it drove me almost bonkers. It is LOUD. If you unplug the unit, the chirping would not stop until you physically removed the battery itself. THIS unit has a mute button, it's the top left button on the unit. I haven't heard the alarm sound on this yet, nor do I want to unplug to test because getting to the plug behind all my computer equipment is a contortionist exercise. But my old APC did not have a mute button, so I assume that's what this is for. There's a feature in the Powerchute program however that allows you to "DISABLE THE BATTERY BACKUP ALARMS AT ALL TIMES" (as well as "Disable the battery backup alarms when the PC is in hibernation"). So you never need hear the alarm if you don't want to, ending the annoyance once and for all. My little APC ES 750 protected my PCs through 3 major hurricanes and 4 serious tropical storms, one of which destroyed my roof. With that one unit, I have never lost a single PC to massive power spikes, something that happens continuously with brownouts as they try to restore power after each major storm to the area. Some neighbors have lost PC's plugged into regular surge protectors. The ability to protect data lines seems to help too, my mom once fried a PC while it was shut down and she was on vacation, the only explanation was a spike through her data lines. The only downside is the weight... to compare it to a brick would be absurd, it is many times the weight of a brick. It's HEAVY. But that's because this is a huge battery and it's all battery weight. Be prepared for the weight, at about 1/6th the size of my loaded tower PC, this weights 4x more. APC are the best, hope this helps!

I've had this UPS Back Up, for two weeks now, decided to check out the software download. After installing, I run the self test and it failed, a small window popped up on my monitor instructing me to contact the supplier to purchase a new $100.00 battery, or skip that and just buy another new one. I ran the test a couple more times, same results. I even tried resetting and restarting it a few times, it kept failing the test. I sent the Amazon third party supplier an email and got back some kind of automated case letter. So then I called Amazon, and they sent the supplier a second email. This time they reply requested my shipping address, so we gave it. Next, day I get a reply from them telling me their UPS website is down and they will contact me again when its working again. So, at this point I had enough and called Amazon back. This time I filed a claim for the return of my money. They told me I should see a refund within 5-7 business days. I guess the supplier will eventually get around to sending a return shipping label if the want their defective merchandise returned. After the fact, I found out this model had be discontinued, even thought they said noting in their sales ad on Amazon about that; And they're selling a new model for twice the price. Hopefully, it will be a better product. Note: This is my second review since I purchased two of these units and both now have failed the battery test. Owning two of these has revealed a pattern which anyone purchasing only one of these wouldn't notice. These unit come equipped with an USB cable which connects from the Battery Back-Up to a computer, software is then downloaded and the user is able to monitor the operation, and perform periodic battery tests. They call this software 'Power-Chute Personal Edition' During the battery test of both units I noticed there was a button for 'Replace Battery Date' I clicked on it and noticed a replacement date of 3/18/21, and 2/18/21 on the other unit. This means as of this date of writing these batteries are already 3 years old! And I've owned these units for a only a few weeks. This would mean the seller is using Amazon to sell off his old warehouse inventory of batteries which have expired dates. The proof is the age of the batteries in these brand new units when tested. This poses a problem because the batteries have an estimated life of 3 years. And both batteries have failed the battery test. In the software, the seller states, "We recommend that you change the battery in your unit at least once every 3 years." If you are one of the unfortunate ones who ended up with one of these defective units, simply contact Amazon Customer Service and explain in detail what has happened here. Even though this is a third-party seller, Amazons A-Z warranty will reimburse you in the event the seller does not refund you if you act within the 30 day warranty period. But, they may even extend the period due to the sellers deception. Finally, based on my own experience with this seller, this seller will try to get you to pay for return shipping, don't do it. If he wants his defective merchandise returned then let him ship you a free shipping label.

I purchased this APC model in 2014 from Amazon and replaced the plug in dual battery pack after 5 years in February 2019. No problems until 29 March 2023 when the internal power supply electronics failed. In Engineering terminology, this unit had an MTBF of between 8 and 9 years after first purchased by me. This new unit is about half the physical size and weight. The battery pack slides in without the use of a plug.. This unit can interface with WIFI via your PC and the APC Software which I have no intention of using this feature. The unit is much quieter than the previous model I purchased in 2014, but when I tested by unplugging the unit, the alarm is just as loud and can be muted. Based on my experience with this model, I rated 4 out of 5 stars, I have no experience with its WIFI usage or with technical support from APC since I never had a problem following the APC installation, operating, and troubleshooting instructions in their very small manual shipped with the units and available as a pdf on their site and on Amazon. Now for my conclusion. I graduated from Drexel University with a BSEE, MSEE, and MS in Engineering Management. I am a retired Power and Power Electronics Engineer with 43 years of experience working 11 years for Siemens and the remaining 32 years for the United States Navy. My experience working for the United States Navy involved the Systems Development, Installation, Operations, and Maintenance of small and large size uninterruptible AC-DC-AC regulated and signal conditioning power sources for the US Navy and Royal HMS Navy ships. In 2014, I purchased over 100 of this APC model for the Navy offices and the US Naval Ships. Those units are just starting to fail after 8 years of service and their internal batteries were replaced after 4 years of service upon my direction to do so, failed or not. The purpose of the UPS is to protect the equipment it supplies and to allow sufficient time for the operators and technicians sufficient time to save data and perform a controlled shutdown. The purpose of UPS Battery Backed up systems is for the above purpose, not to remain operational for long lasting power outages. For long lasting power outages, a combination of a fuel operated AC Generator and UPD can provide power to provide power to electronics systems. The APC UPS systems should never be used to provide inductive loads such as refrigerators, blower fans, and air conditioners. Inductive loads can be posted only by generators or very large UPS Systems designed for linear, capacitive, and inductive load centers.costing in the tens of thousands of dollars and higher. I recommend this APC model for supplying small size power to only electronics equipment. Any technical questions should be directed to APC technical support, not the sellers. When purchasing any equipment is always best to direct technical questions to the manufacturer and not the distributors and retailers. Any power electronics engineer is also a good source on what to buy and those with a lot of experience are a good source on from whom. Again APC is a quality company who backs this mode with a 3 year warranty. My guidance is that out of a 100 units, the older model lasted for at least 8 years before having a failure, and I recommended replacement as soon as they failed. Most electronics and power electronics equipment have a life expectancy of between 5 and 10 years and dependent on the quality and manufacture design. Large manufacturers usually have the better design engineers as well as the better quality control. My first 11 years was as a destructive test engineer to determine design flaws and life expectancy.

Bought this for home network backup. It's large enough to keep internet/wifi up for a bit over 3 hours. I have a separate UPS (also an APC product) for my wireless phones and VOIP adapter. Power has failed twice since this was purchased. Yes, it WORKS. Not real cheap, but very, very useful.

I have purchased two of these after having problems with some of my computers after power outages or the power flickering on/off. I have one for my gaming PC setup and the other for my router. These UPSes are awesome, keeps your computer running during a brief power outage, and gives you enough time to gracefully save and shut down during a longer power outage. There are a few minor things that I don't like: - When plugged in and the power is on, this UPS makes a faint chirping sound every few seconds. It's not super loud and sounds like a bird outside your window, but when the room is quiet it can be annoying. - When running on battery, this UPS makes a faint hissing sound, similar to an old TV. Again, this isn't super loud, but during overnight power outages this typically bothers me and I have to turn it off. - The relay or whatever they use for switching over to battery power is quite loud. This UPS is pretty sensitive to any imperfection in the power supply, and sometimes in the morning I am awoken by it clicking on/ off a few times. Here are the run times I have observed: - It can run my router for about 2 hours - When not gaming (using about 200 watts), it can run my gaming PC setup for about 30 minutes - When gaming (using about 500 watts), it can run my gaming PC setup for about 10 minutes
