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

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

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

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

No problems, worked as expected

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

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

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

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

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

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

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

Bought this one to replace a failing Battery Backup.

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

Not as bad as I first thought

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

It provides proprietary features that just aren't going to be provided by your OS natively

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

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.

The display panel shows the load on the UPS which is a useful feature.

I considered the equivalent Cyberpower model, but it appears at the time of my purchase the APC is the better value, and it looks like the AVR functionality is a little better on the APC with both overvoltage and undervoltage protection.

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

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

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

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

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

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

Great display for information showing how much power is being used and more juice than most APCs.

What I noticed is the whine is slightly louder and the frequency slighly lower when you press the LCD display on - but the display automatically shuts off after 60 seconds and that whine pretty much goes away

I also like it has "master" and "slave" outlets; backup outlets and just surge protection outlets.

They are a good alternative to a power strip, as they function as surge protection and UPS

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

But my last purchase failed by killing my land phone line for 2 days until I found that the problem was in the BR1000g

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

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

My old APC 1400 had served me well over the years but when the UPS started complaining about the battery not holding any longer, I started looking around for it's replacement

Great UPS so far, it's already saved my computer while the power was out.

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

I have been a loyal APC UPS customer for over 20 years.

This is a must for those of us who live in NYC - Con Ed in NYC sucks beyond belief: high rates and lousy service

Excellent customer service and excellent product will buy again

In a world with very bad customer service and poor follow-through from just about every manufacturer, and painful RMA /exchange processes, APC is almost Amazon-like with regards to great customer service and honoring their manufacturer warranty

My experience was out of the ordinary but they still provided excellent customer service

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

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 very well, shipped quickly, and exactly as described.

Furthermore, CyberPower has made myself and friends PAY to ship defective units back to them in the past, while APC handles warranty returns and exchanges for free (which is critical for shipping a heavy UPS that equates to expensive shipping)

It is quite heavy, and batteries have very restrictive shipping rules.

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

Like all APC products I have used works great and very reliable.

I have been a loyal APC UPS customer for over 20 years.

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

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

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

Disappointing because it seems like an otherwise great unit

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

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

This is a great unit, I like the number of outlets and it's capabilities.

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

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

If even only one battery is bad, it will drag down the system so it can't provide power for very long.

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

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

Great battery backups that have easy to replace batteries when they get old

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

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

About a month after purchasing this UPS, it started giving alarms about failed battery tests.

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

would recommend before running the "self-test" feature you could get false test results) ran several tests all good

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

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

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"

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 first one I use to keep my networking hardware running in the event of a power failure

Overall I highly recommend it as I have had many of these over the years and they have never let me down.

so it doesn’t drain the batteries and rely on the UPS in case of a power failure

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

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

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

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

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

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

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

The noise is loud enough be annoying in an office environment.

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

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

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

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

This product is absolutely wonderful and has solved all my power interruption problems

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

Keeps me going when those frequent power interruption knock other PC's off line.

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.

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

Got tired of power flickers resetting cable box and modem

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

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

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

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

The unit also makes a whiny/buzzing sound whenever the screen is on, but that goes away when the screen turns off.

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

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.

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.

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

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

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 have had 2 power issues since purchase without failure.

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

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

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

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

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

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
