APC Back-UPS Pro 1500VA UPS Battery Backup & Surge Protector, BX1500M Backup Battery Power Supply

Arrived quickly, well packaged, no complaints at all. Compact model, has been redesigned from when I last looked at these units. Connecting the battery for setup was a breeze. Simply flip over, and open the bottom flap. The battery is actually two batteries joined. They have two large stickers on either side, one red one green, that each have two tabs on them that you use to pull the battery out, flip it over so the green sticker is showing upwards, which then lines up the built in connector and slip it back into the unit, replace the bottom flap. Viola ! Seems to take a little longer than I remember to initialize, but that is no big deal for me. Comes with a testing report, dated 7/2025. Battery was charged to around 55% so I left it overnight on charge before connecting anything to it. Will report back if there are problems, but as of right now, unit is happily charging, no issues.

This is a physically large unit and it will handle quite a few items plugged into it. I've had no problems with it. It supports a desktop computer, a laser printer and two 3D printers without any issues.

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.

I'm giving this 5 stars even though I needed to get a replacement. The first one sent over gave me error codes on the display and was obviously defective. I had amazon send me a replacement and i dropped off the defective one. once i got the new one, 2 seconds after installing the new one it was flawless. Even had a storm that made the power go out for a couple seconds happen later that day and it was like nothing ever happened. This is great for anyone that has a gaming computer, i have pc with 2 monitors that are both high refresh rates and under full load in a game i can chug almost 800w of power. This handles it like a champ. If you are someone with a 5090 or some extremely high wattage card that is above 400w you should go for a 1000w+ UPS. A UPS is a must have if you live in an area where weather can turn in an instant or have frequent storms. Set up took 2 seconds, just make sure you flip the battery as it comes disconnected.

First one I receive happened to be old inventory and simply did not work; battery could not charge. Contacted support and they were awesome in getting me a replacement right away. The replacement has been working since July, but it's developed a noticeable coil whine that started around November. I can unplug it and discharge the battery a bit and it'll go away until it is fully charged. Eventually it returns and whines. Install and setup was pretty straightforward. Looks nice on a shelf in my server rack. Haven't had any power outages or brown-outs but I feel peace of mind knowing my homelab is protected.

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.

great product at a nice price. the first time it kept the wifi on during a power outage; proved a second one is necessary to support media in the house. much needed during emergencies!

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!
