The unit has worked as expected on the two occasions we've had power blips in our rural community.

WE had our first power outage a few weeks ago and the UPS worked as expected

Works as expected, we have occasional power outages and all the electronics automatically switch over to this battery.

No problems, worked as expected

My inverter just doesn't have enough power by itself or clean a/c

Other companies are certainly improving, but when it's critical I always go with APC.

Auto-shutdown, AVR, and other high-end features at a great price.

The price that you pay for this unit is small compared to the cost for equipment damage or recovering lost data.

:I received a defective BR1500MS unit from Amazon in May 2018, but I didn't want to return the product because I got it for a great price on

Amazon offered a great price for this UPS versus competitors, and I knew that this UPS model is fantastic overall

They always have a life which far exceeds the shelf life advertised for the product.

Worked as advertised if you want to get a real hour of use from your whole system buy the add on battery

This UPS appears to work as advertised, and as my scope shows, it puts out a relatively decent true sine wave when on battery power - definitely not a stepped sine wave.

You would hope that Amazon would have newer inventory of these units, or that Amazon wouldnt knowingly carry defective units, but clearly from the reviews on Amazon, it's still hit or miss as to whether or not you will order an APC BR1500MS (or BR1000MS, etc) and get one that doesn't chirp

Easy installation, Already had some power outages and working as advertised

It has provided enough backup so that I have never needed a shutdown.

great backup for my security camera system. lasts a good while.

Very good battery backup, if your running something that is not too power hungry, it will run it for over an hour

Power outage at the house (Storm), lost connectivity (router, etc.)...the "U" in UPS is false with this thing

but it's annoying as much for having to press the button as it is for losing a feature that the old one did well and wouldn't have have been hard to do for this one too.

Had to turn off the "smart" power feature, but it's been solid

A nice feature is the digital display which shows you some operating parameters as well as a count of power interruption events.

The unit is solid and good values with AVR for brownouts

The battery will still bleed even if it outside the APC but not as fast as when it is inserted in the usable position

mine works great looks great but smells like cat urine...strongly....have had it out in a open room for several days its still as strong as ever...wonder if its battery acid?but smell aside this is a great value

Useful display shows how much power computers consume and how much time it will work offline

The UPS has an LED display letting you know how much current is going through your system

I was expecting the display to be a gimmick, but it does provide some helpful information about the current load, remaining time on battery (based current load), etc

I like the display that shows time left on battery use, power in, and power out

Power outage at the house (Storm), lost connectivity (router, etc.)...the "U" in UPS is false with this thing

Five outlets have surge protection only and five have surge protection and power backup

Had a chance to see how the surge protection of this unit works when lightning struck the power pole outside our shop recently

Other companies are certainly improving, but when it's critical I always go with APC.

The surge protection for power and ethernet worked fine.

It's good because it's a good UPS, bad because the replacement battery cost almost as much as the new unit.

APC has a three-year warranty, and replaced the UPS for free when it failed

I replaced a failing APC UPS which was about 12 years old

I do not know if it is truly a battery issue or if the UPS is defective.

This is a good UPS, but note that this will not save you from power surge

Other companies are certainly improving, but when it's critical I always go with APC.

I've used APC professionally for years and they make a great quality product, and back it up with great service if you ever need anything

Cannot recommend this product due to poor customer service.

I am happy to know they have excellent customer service, or at least in this experience for me.

Excellent customer service and excellent product will buy again

Works very well, shipped quickly, and exactly as described.

Most likely not worth the shipping to send it to APC and wait for weeks if not months--weighs more than my first car

So again without my asking, my APC rep provided me with free overnight shipping on the delivery of my new BR1500MS unit, to cut down on the wait time for getting my replacement

Batteries in the units seem to last about 1 year and a half in my experience and replacement batteries are easily ordered via Amazon.the free prime shipping alone on these is worth the prime subscription cost, although my UPS driver may not agree.

These can be found cheaper elsewhere but amazon ships this heavy beast free, and if you get a dud just send send it back

Works as well as all other APC units at a reasonable cost.

UPS itself works great, however APC has serious quality control issues.

I returned the "defective" APC Back-UPS Pro 1500 and got a new replacement.

I easily re-packed my defective APC UPS in the box that came with my new unit, then I slapped the free return-shipping label on the box and brought it to a FedEx drop-off location

UPS itself works great, however APC has serious quality control issues.

The unit has an alarm that goes on when the power goes off

this have me wondering if the initial battery pack was new or if I'm using a defective unit

It also helps because I can use the packaging to send the defective unit back

This unit is also great to keep the internet and network up and running during a power outage.

This is a great unit to provide battery backup / power protection for my old TiVo and digital tuner

So then we get to the "bad battery" that the unit detects.

Very good battery backup, if your running something that is not too power hungry, it will run it for over an hour

At that point the battery kept testing bad, with a rare one in there testing good.

I really like that there are outlets that only have surge protection and do not drain the battery.

Frequent Florida lightning strikes require the best Surge Protector available, and this unit has a great battery backup if local power should be lost!

Worked fine for the first little bit, but every once in awhile the battery would fail a self test, then right

They don' t require much power, like the Bridgeport mill and Republic Turnmaster lathe they serve

Battery failed self test after one month of service with no power outage events

So far my testing has gone well, and my NAS shuts down and restarts when the power is restored.

They don' t require much power, like the Bridgeport mill and Republic Turnmaster lathe they serve

The next two units fail it's automatic self tests, goes into a fast chirp warning, and needs to be manually tested (HOLD power button for 6 seconds) to clear the error, this happens every 14-40 days

As others have indicated, this unit has a rather atrocious constant high-pitched whine that periodically (once every few seconds or so) ramps up into a louder "chirp"

 Exhibiting the same annoying chirping sound every few seconds that others have mentioned.

I wanted to purchase from Amazon as they offered a great price on this APC BR1500MS unit, so I ordered the unit knowing that 'older' manufactured units had the annoying chirping sound, but hoping that I would be getting a newer-manufactured unit without the defect

The unit looks and feels very nice, but this chirping is so distracting that I can't use it right now.

The instructions need to be improved as they seem to be disorganized.

The second unit will not hold a charge after experiencing one brief power failure.

i have a major computer network and this UPS is the only one that will keep me up and running in a power failure situation of more than 2 minutes.

Mine does it but it does not bother me as much as it bothers some of the reviewers.

One power failure corrupted my wife's computer data without a UPS (so I had to restore the operating system)

Despite what the seller says in the questions section the high-pitched whine is NOT fixed

These machines also have state of art computer controls that require clean a/c current

They don' t require much power, like the Bridgeport mill and Republic Turnmaster lathe they serve

As many people have stated, there's a high-pitched whine from the unit

There is a relatively loud, continuous, high pitch whine that is unacceptable

It's a quiet noise, but unbearable in a quiet environment

Mine was produced in February and produces no audible noise once charged

The noise is very quiet, but just enough to hear it if you are sitting nearby

There is one major flaw with this APC, it makes an annoying noise every 4 seconds.

Sadly, I wound up with a defective unit making this annoying noise

And you can turn off the beeping easily and quickly if there is a power interruption.

After a power interruption today this unit no longer functions.

They don' t require much power, like the Bridgeport mill and Republic Turnmaster lathe they serve

They don' t require much power, like the Bridgeport mill and Republic Turnmaster lathe they serve

I do not hook up my computer to it, so the backup capacity should be very adequate for a few hours of power interruption.

These machines also have state of art computer controls that require clean a/c current

Before this, I really couldn't use a desktop computer as the power flickers too much.

My inverter just doesn't have enough power by itself or clean a/c

I'm watching a TV show, the power flickers, I have to sit and wait 5 minutes while the cable box resets.

I have a couple of these now, our power flickers quite frequently and this keeps everything running.

To test the system, I disconnected the power, and the battery lasted for over 2 hours of use with the TV on vivid display and the sound at a fun level for watching movies with a friend

If you wake the display on the APC it makes an even more annoying buzzing sound.

Also of note, the unit does make a rather loud buzzing sound when it fails over to battery.

Thankfully, the annoying beeping sound can be muted on the front panel

The battery drained, the unit On/Off switch was unresponsive and began making a strange sound .

I bought this UPS unit to keep the server and desktop from frying their hard drives during these power cycle events

I have two computers systems (one is used only rarely), the above modems and an external hard drive.

ONI'm using this UPS to power an iMac 27inch Retina, (3) external 4TB hard drives, an Airport Extreme WiFi router and a cable modem.

This APC 1500VA UPS now keeps my iMac and numerous hard drives up and running when the power flickers

This specific model is great for a single computer with monitor and one external hard drive

Never worry about power surges, brown-outs, or other typical power issues again.

You can track long term power issues and usage by using the software.

we appeared to have no power issues with our critical gear.

I've had lots of UPS, and when there's no power issues, they're like bricks, just out of the way

I have had 2 power issues since purchase without failure.

I've seen occasional unexplained power loss to my desktop, intermittent buzzing or clicking from the APC unit, and several false alarms where the unit believes it has no power even though it does

That means the expected standby time during a complete power loss is around one hour, even while using the computer.

You can even turn the screen to stay on, and the power loss sound off

Also, if power is lost, the software that was included will shut the computer down before the unit runs out of juice, ensuring that my machine doesn't try to keep going after a power loss

I experience the "chirp" that the other folks that left reviews are also experiencing (included video)I purchased 2 units 1500VA and one 1000VA both experience the wonderful chirp that is a little annoying when they are together.very dissatisfied with both of these products as i've owned other APC units that run completely silent until under commercial power loss.*added to
