APC UPS 1500VA Sinewave UPS Battery Backup, BR1500MS2 Backup Battery Power Supply, AVR, 10 Outlets, (2) USB Charger Ports

So, I got a Cyber Monday deal on this unit, and it's been one of the ups's that I have been researching and watching for a while. I currently have an old/obsolete APC BN1080G running all my network equipment. This unit works great for this purpose since we have numerous power outages during the year, and power surges cause by stupid squirrels getting fried on power lines and transformers. I am on my second set of batteries on the BN1080G and it keeps on working great. So, I decided based on that to purchase this BR1500MS2 for my computer and monitor. Desktop PC would now be protected with a sinewave ups. So, pros for this unit are as follows in my situation. 1 Sinewave output 2 1500 va and 900w capacity 3 APC reliability 4 Decent footprint 5 Reliability based on current unit is a big plus. Con 1 When will APC update products to LiFepo batteries. 2 Yes battery replacement every 3-5 years depending on how deep and often ups switches to battery. Lots of switches with deep cycles get battery replacement close to the 3-year mark. Powered up unit when received to charge batteries and to see if there were problems with unit. There is an electronics smell when powered up and over the course of a day and a few load test the smell has not disappeared. I hope this goes away after a few days. I have a Threadripper desktop PC, monitor, and nas station connected to ups. So far, ups is running cool when Threadripper goes to work. Ups does not get hot when 300 watts of peak loads are applied. No buzzing and other noises are coming from ups. Software install has been completed. My BitDefender antivirus software flagged this software as a possible bad player but went ahead and setup rules for it. One thing I wish software would allow would be a shutdown test without pulling main plug from wall. That would test software`s ability to shutdown pc. Hate pulling plugs to test. The test cycle in the software for switching to battery backup works well though. The other item would be to see more than one ups in the software so it could either control it and or provide the same data as other ups. Software is designed from what I can see to control and monitor only one unit. So, with this all said, I got a great deal on price and delivery was overnight. I would like to test a lifepo battery unit someday to see if the hype is real, but that would require one on my APC ups units to fail which I am confident from many years of home and commercial experience might not happen too soon. Amazon AI wants more answers. It does weigh a good 27 pounds. Protection level with new unit will have to wait till first squirrel fry or power outage which will happen soon since it`s wintertime. Size is perfect. Small footprint and case have plenty of venting to keep cool. Will update review in a few months if something significate happens that needs to be communicated. 12_10_25 update. Smell still there and it does get worse with load. Contacted Schneider Electric and told them what was going on, and they have authorized a new unit to be sent to me. Now that's the kind of customer service you can praise. While talking to service advisor we had 2 power bumps from nasty windstorm that we have going on, and unit worked flawlessly and my desktop kept on going without a flicker. Looking forward to new unit that doesn`t smell like the end of its life could happen at any time soon. Again this unit is working well except or the electronics smell. Would buy again if another ups is needed. 12_17_2025 update. Received replacement and got it all charged up just in time for the latest windstorm. This one too smells of electrical components that are hot or got stressed during burnin and testing. This one's not as bad and so far, does not seem to get smellier with increased load. Hope this smell goes away because it's too cold to leave window open to air out room. We did test unit with a power bump from something hitting power line during the storm and unit worked. So would I buy this again. Not sure now with the sink issue perfectly. Hope smell is gone in a week. Would I still recommend? Yes, if you don`t mind the electronic components smell. This is 2 for 2 and I don`t see this as a one-off issue. Will keep using and hope it makes it 3 years and with summer 6 months away, I can open windows and air the office out. I will say that the customer support has been outstanding, so you have that on your side.

I have used APC UPS of various models for many, many years. They have always performed as expected. I currently have the Back-UPS Pro BR1500MS2 and it works perfectly. I'm writing this review not so much so about the UPS, but more for information on what to expect if using this UPS with a portable generator. I am an IT Senior Systems Engineer working from home for the last year or so due to Covid. I have a very highend computer system thus the reason I am using the BR1500MS2. My system draws around 450-500 watts constantly and this UPS supports it just fine. Ok, now on to my point. I live in Colorado and if you remember we recently had a very bad wind storm which knocked out power to most of us in central Colorado for several days. After the second day of no power and no heat (house was 39 degrees). I was pretty much forced to obtain a portal generator. This generator was a highend 8650 Watts from a reputable company. Generator performed as expected - Frig is working, got coffee, have some heat - all good. BTW we were without utility power for 8 days. Wife is happy again, so now it is time to get the computer system and network back on up and running. Here is where you need to be AWARE of using a UPS with Generator Power. I plugged the UPS in to the generator power. Turned on the UPS and after a few seconds, the UPS started to cycle from Gen Power to Battery Power back and forth. That's strange, what could be wrong. Well, it wasn't the input voltage from the Generator - Checked it to be 115v continuous, but UPS still cycling. AH HA, it was the input frequency. The UPS is rated as input frequency to be 60 +/- 3hz. The display on the UPS indicated it was receiving 63hz. So apparently, the Generator was outputting just a hair outside the 60 +/- 3hz range of the UPS specs and causing the UPS to cycle into and out of battery mode. Obviously, it was designed to do this. Ok, unplug all of the stuff from the UPS and plug into generator power and all is good. I need to talk with the generator manufacture on getting the output frequency adjusted no doubt. Sorry for all of the blah, blah, but I wanted to set the expectations if you have an operating environment where you must use a UPS with generator power, you may find yourself in a situation where things may not work as expected due to input/output thresholds of your equipment. Oh, and by the way, the generator manufacture said the Gen was operating within their specs 60hz +/- 3hz. Apparently, the UPS or GEN is not exactly within specs. UPDATE for BR1500MS2: I recently had the need again to use the UPS with my generator. Utility folks replacing power pole, so I powered up the generator to keep a few things running. As I had mentioned previously, I was having an issue with the UPS staying online using the generator voltage. After reading some additional detail about the UPS Sensitivity settings, I adjust the setting from the default of Medium to LOW. The definition of LOW is "Use this setting if your battery backup continues to transfer to battery operation frequently on the medium setting. Typically, this occurs when the AC utility source is a generator. Caution, this will allow greater voltage distortions to reach your computer." Ok, so why couldn't the support folks at APC advise me of this. Maybe because of the caution notice - who knows. Anyway, I set the sensitivity to Low, connected the input of the UPS to the generator output voltage. Ah HA, this time the UPS stayed online and stopped the frequent switching on and off line as before. I monitored the UPS output to my computer and only noticed a small variation in voltage and HZ. Not enough to cause any harm to my system. After utility power was restored, generator off, I put the sensitivity setting back to the default Medium. So I just wanted to update my previous entry about using this UPS with home generators. It does work afterall, just change the UPS sensitivity setting.

Update: 08/24/2025 One year in, and things are still fantastic. The UPS went through a couple of real power flickers, some power fluctuations usually undetectable before storms arrived, and a real power outage that lasted me about five and a half hours recently. Unfortunately, I was not home to switch the UPS to an alternate power source, but was able to begin charging it once I did arrive home during the power outage. No battery replacement alerts have sounded yet, and the UPS has been testing its own battery, something I was awake for one morning to hear relays clicking. Everything is still working exactly as intended, and the UPS has been successfully providing uninterrupted power to all of my devices. Original: 08/07/2024 This UPS works very well for my use, powering all the equipment I use on a daily basis. In fact, the power from the UPS seems cleaner than what I get from the grid, even though it's not really conditioning the power, that I'm aware of. I'm merely going off the fact that my analogue receiver's transformer humm is a little quieter and sounds ever so slightly smoother than it usually does, something most people likely wouldn't notice. I've also had no ground loop humming while connecting or disconnecting devices to my mixer, or while using the inverter in the UPS itself. After receiving the UPS, I was able to figure out where the battery door is and open it to connect the battery, then I connected it to power for a couple hours with no load on it, allowing the battery to fully charge as indicated by the UPS, though it likely still had several hours to go until a complete charge was achieved. I then disconnected the UPS from power, receiving the pleasant sound of four beeps every thirty seconds that will probably wake me up at night, a good thing, since I'll transfer the UPS from its battery to another external power source if the power is out longer than a few minutes. After verifying that this worked correctly, I connected my serge protector to the UPS after connecting it to power, which has my equipment connected. One Asus laptop, an audio mixer, wireless headphones, two USB hubs, one of which isn't being used, an old analogue receiver and equalizer for my sound system, a TV which is usually off, an Apple TV, a modem for internet, a computer for my router, a router for a Wi-fi hot spot, and a USB-C charger for my MacBook Pro. Under normal circumstances if I'm not using the receiver, though it's usually on and waiting to be used, I'm probably pulling about 150 watts from the UPS. According to APC's information and calculator, this will probably provide around 45 minutes of run time, so this should give me plenty of time to wait and see if the power is going to stay off, and if so, switch to a larger battery to power the UPS itself. I did test this, and it does work, at least, with a pure signwave inverter. If I need more runtime, I can extend it by powering off everything I'm not using. My receiver and equalizer, for instance. So far, everything is very stable, I've had no difficulties, and I'm anticipating a battery replacement in about three to five years, typical with an SLA battery, as long as you're not deep cycling it and keeping it on a well maintained floating charge most of the time.

Review: I’ve been using the APC 1500 MS2 UPS for around a few months now, and overall, it has exceeded my expectations. Here are some key points: Pros: • Reliable Power Backup: Provides consistent power backup during outages, allowing me to safely save my work and shut down equipment properly. • Sufficient Battery Runtime: The battery lasts long enough for short interruptions and even extended outages with moderate load. • Multiple Outlets: Offers ample outlets for my computer, monitor, and peripherals. • User-friendly Display: The LCD provides clear info on load, battery status, and input/output voltage. • Build Quality: Solid, compact design that fits nicely on my desk. Cons: • The UPS is a bit bulky, which might be an issue for tight spaces. • The fan can be noticeable under heavy load, but it’s not disruptive. Overall: The APC 1500 MS2 is a great choice for anyone looking to protect their electronics from power fluctuations and outages. It’s particularly good for home offices and small business setups. I highly recommend it!

These are great for short power outages (15-20 min) or places that have inconsistent/surging power supply. But these are only good for about 30 min for things like Wi-Fi router/modem, NVRs, or computers (and I mean or, not and. If you run all of those things on it you're lucky to get 10 minutes). They can't run things for very long, especially higher watt electronics, and I feel like 30 minutes is being generous based on my experience relying on these during power outages. I've had to replace the battery on one unit after only 2 years. As a surge protector, these are great, but there are definitely other products out there that are better if you're looking for a longer battery backup.

This thing has saved my PC from sudden power spikes multiple times in the last year alone. I actually can't imagine not using a backup battery anymore. I took a star off because the usb-c port stopped working suddenly and I have no idea how to fix it.

Usual stuff - got F02 error code in 2 months, which a lot of people are complaining about. This thing is less reliable than power in my house, so what's the point? Didn't even last till the first power outage... What happened is a loud pop, smoke and smell of popcorn out of the blue followed by a constant beep with the error code on the display. Yes, that's right, there was no power outage or anything, all devices in that same room continued to operate as they should, except for those plugged into this so-called "UPS". Since warranty only lasts 1 month and mine was past the deadline (you have to pay for shipping to the service center after that) - I decided to become a good Samaritan and save people money. Let's find out what F02 actually means and why we got it! Disclaimer: I don't have PhD in electrical engineering, but I did complete a high-school physics course, so I have some basic understanding of electric circuitry. Given that this device is not a 10nm silicon die and all components are finger-sized - we should be good. After opening the device we find what appears to be a typical PWM inverter with four MOSFETs laid out in a bridge topology. Yeah, "pure sine wave" should be in quotes, because it's still your typical pulse-width modulation that converts DC to stepped AC sine. Either way, after revisiting all components on the board, we can see that two back MOSFETs in the bridge cracked-open themselves. Transistors they decided to use are Infenion IRFB7440, you can find a datasheet in no time. First and foremost, these are 40V, that's it: +/-20V. The battery in this UPS is constructed from two "CSB UPS 12580" batteries connected in series. This is a 12V battery (mine fully charged reads 13.06V), so two connected in series gives you 24V per spec (and 26V in my case with brand new batteries). No surprise MOSFETs are in the state they are in. I frankly don't know how it was supposed to work, but whatever, lets move further down the MOSFETs spec... Max power dissipation is 143 W, we have a bridge, so 2 MOSFETs are active at a given moment of time, which gives us 286 W. Hm... yeah, I understand that it's not that black and white and depending on the operational mode transistors can sustain different power levels, but pulse modulation at 60 Hz is not a walk in the park - they have to open and close pretty fast, so I think we are working at some levels close to the max and they are over-volted. :/ I'm waiting for new MOSFETs to arrive, but one thing for sure - I'm not going to hook anything important to it and I wouldn't suggest you to do that either. With all honesty, these are high-powered devices, there is high current flowing through them. Given that they all made you know where these days - I wouldn't leave them running unattended... p.s.: It is worth noting that this device doesn't have a physical power disconnect switch. Power button is a "soft button", so this thing is "always on". You can witness a spark when you connect the battery (which ideally you shouldn't), because the circuit immediately closes to power the controller. I'd say that's a bad design as well - they should have put a rocker on/off switch on the back, so that you can safely plug in the battery. To provide some clarity - what you see on the pictures is "MS2" (aka "upgraded") model. I can only imagine what the original "MS" model was. Before Amazon removed their comments feature, there was a comment from APC representative, saying that I probably got the "MS" version - no I did not. That person also claimed that "MS2" version was "improved for performance", whatever it means. Finally, they suggested me to contact the support to get a replacement at no cost, which I of course did, but they never got back to me after I told them it is "MS2" and it burned in flames. Their typical response is probably to replace "MS" with "MS2", which doesn't help a bit. I wish I could get an original "MS" instance to compare the difference in the components they have used, because at this moment it appears that "MS2" is just a "placebo".

I have 9 or 10 UPS systems in my house. I typically use APC units for my computers as their longevity in the industry, enterprise products, and overall name are synonymous with uninterruptable power and protection. This unit is no different. When I do lose power, which doesn't happen often, I have more than enough time to finish what I was doing and shut things down. Highly recommended.
