I have pulled power cord and it works as expected on simulated power outage.

So, the new battery does work, but certainly not as expected

Replacement was a fairly quick process, size was perfect fit, would be really easy if the positive cable wire was 1 inch longer.

Came quickly, easy fit resurrected good old part of in home system surge protector.

Perfect fit and works great, got it on time and was packaged very well.will buy again for sure.

Perfect fit, arrived on time and my old APC works again.

i do not expect APC to make batteries and this fit and worked immediately, plus half the price buying on APC site and free Prime shipping.

APC does have a free shipping label you can print out to send your old one back

Was so happy to find this replacement battery through Amazon - lower price, free shipping and friendly return policy

Worked perfectly with APC UPS; great price and free shipping with prime.

Great price on these and the shipping was much faster than I'd expected for batteries of this size.

As expected, this battery was a perfect replacement for my wife's APC ES650 UPS..... exactly the right size and the terminals in the right place.

If you have an APC BE750BB UPS, this battery is physically not the right size.

While it is the same size and may work just fine, it is not the genuine APC brand battery as advertised.

Replacement RBC17 battery fit as advertised, terminal connections are the correct size & type

I purchased this replacement battery and it was easy to install and has worked flawlessly since it was installed.

The install was easy after I watched several YouTube videos.

This replacement battery arrived promptly and was an easy install.

Battery has been installed in UPS for about 4 weeks, UPS works great.

With this battery, it had the APC sticker on it and when installed, the UPS gave no protests, warnings, beeps or anything else.

My UPS seems to be working great with this replacement battery.

Installed two of these in two APC backup systems that have been working well for many years.

The battery is identical to the original battery and has worked great for the last month

Perfect fit and works great, got it on time and was packaged very well.will buy again for sure.

Replaced dead battery and my back up works again.

Great battery, easy installation just follow instructions

Perfect replacement battery and easy installation on my APC backup that I had for over 10 years!

But gee whiz, installation was HARD.

Works as advertised and nice replacement for mine that finally wore out.

Works perfectly as advertised and helps me maintain the warranty on my UPS

Work as advertised and hold charge enough to power a 3d printer or a computer, not for too long though but enough for my needs.

I am very disappointed that amazon.com has chosen to disregard those reviews and continued to allow false advertising/marketing on their web site.

Part looks to be from old stock but worked as advertised

We liked the quality, durability, and dependability of the product

Off brand batteries that were cheaper were of unknown quality.

As for the battery itself, as always the quality of APC is excellent

This product arrived a little late, they were technical problems of USPS.Packing with very good quality, as it is usually with Amazon products

This battery died after 1 month of use and it's supposed to be a genuine APC battery.

It has the standard APC label with no marks, scuffs or any

No problems though, I contacted APC and they sent out a replacement

Decided to splurge and by a genuine APC battery since my backup stopped working.

I believe it's a Genuine APC replacement battery, only product label has APC as in the picture, if it's made by another manufacturer for

It is a Brother MFC 8900 CDW printer and it has to be reset at times, and I'm not sure if it's because of a power surge/failure or poor product design, but I suspect the latter to be the cause.

This battery arrived quickly via ground shipping, and overall appeared to be a genuine APC product (e.g. APC cardboard box, APC labels on the battery, only minor labeling differences between this and the original UPS battery).

Looks like a common problem with this "Amazon Recommended" product

The product was delivered on time and worked as it should.

The UPS is a fine product but the battery cartridges do not live up to the advertised life

my UPS lost a volt and i could not get it back up since this was a sealed battery.

Be sure you have correct UPS & battery model match-up; the APC web site has charts for this if needed.

Included a link for a free UPS return label to recycle the old battery.

Battery has been installed in UPS for about 4 weeks, UPS works great.

The replacement battery pack was a perfect match and my UPS is working fine again.

So glad I went with this genuine APC replacement battery

Shipped in an official APC box and by all means appears to be a genuine APC replacement battery.

Replaced my old battery in my APC UPS unit and it worked great!

I received a dead battery and they would not exchange it

Used this product to replace a dead battery in a apc unit.

I'd expect something like that to happen after at least several months of use and several power failures, not just a few days with no power failures at all

Works like a charm, however, we won't know exactly until we have a power failure.

The modem has not been offline at all because of power failure.

Works as it should.

Stopped the annoying beeping on my UPS, doing its job nicely :-)

First battery lasted 8 years the started failing the test and beeping weekly.

Bought one in 8/2017, stopped working with annoying beeps and had to buy another in 6/2018

Something went wrong in the factory bacause my batteries and new set started beeping and failed within an hour of a power failure.

Now, I cannot give the rave reviews and recommendations for APC.Just over an hour when the beeping increased to a scream and then died
