We had problems with the replacement battery and called to either get replacement or to return product.

Check your unit- mine had a manufacturing defect

I've had my unit for years and the battery finally gave out. By chance I used an outlet tester on it and was surprised to find that one of the backed up outlets showed "open neutral". I opened it up and saw the problem. The metal bar inside that has clamps that grip the plug didn't have the clamps for this outlet. The defect is circled in blue in the photo, it should look like the one circled in red. The unit has worked for me for years, just never used this particular outlet on it I guess....

APC Power Back-UPS - Outstanding Product

We've been using APC Power Back-UPS since we got our first computers in 1997. We use them to back-up our computers, DVRs and TVs. We currently have 4 APC Backup Units. They are very very well made, reliable and are outstanding products. One of the benefits of having them, in addition to having continuous power when there is a short power failure, is that they have replaceable batteries. The unit I finally had to replace was approximately 20 years old.

APC units work well

Keeps the electronics safe from power fluctuations. Been using APC products for 30 years and they never dissapoint. Used trade UPS program to replace the 8 year old unit with a new one for a bit more than the battery would have cost and the old one ships back for proper disposal!

Critical Equipment

This is an absolute must have with any computer system, and a solid dependable investment to protect your equipment and data.

Great product

Love APC products. Have always been a fair price, high quality, dependable and last for years. Use them at the office and at home.

Back-UPS 550 APC Unit

So for so good. Just installed the device within the past week for a computer and other hardware peripherals attached to it.

APC Back-UPS ES 8 Outlet 550VA 120V - Replacement

This unit is a replacement in kind for an existing unit whose battery was getting low and not charging correctly after 5 years.

Great Unit. Great Price. Would purchase again.

Ordered on the company website after a search and it came quickly. Was an upgrade perk from an old unit when I planned to order a new battery. For twice the price of a battery, I purchased this. It's got more backup outlets and filtered outlets (4 instead of 3). Nice and compact. I've already got every outlet used. Has already saved me once. I'm very pleased with my purchase.

Reliable Brand

The device works as advertised. No mus, no fuss, just reliable protection. I have 10 APC devices deployed in my home. There is a reason. I have tried other brands and always find myself comparing them to APC brands.

Satisfied, as is usual

As always, this UPS was packaged well, installed easily and is working fine.

Great Power Protection

small enough to fit under the desk; outlets spaced far enough apart for more functional use of adapters; easy battery access; solid construction; good for few minutes of power to keep my devices from sudden shutdowns or electrical surges.

One more time

This is my 3rd backup poer supply from APC. My compliment is that it does what it is suppose to do and I never worry about it.

Works great except for the annoying audible alert

The APC UPS 550VA did what it was supposed to do during our recent power outage. It seamlessly switched over to battery power when AC power went out. I had plenty of time to wrap up my work and shut down the computer safely. However, the audible reminder tone was frequent and absolutely annoying after a few minutes. I had to turn it off to save my sanity. Later when our cell phones needed a charging, I had to move the UPS to the garage to charge the phones. This was extremely inconvenient ...

Easy

I'm no techno person but I figured out this power supply exchange and set up easily.

Decades long relationship

I've been using APC UPS devices for decades, periodically swapping out older ones for newer ones. I use their UPS devices for my computer systems as well as for my stereo and television.

Durable

[This review was collected as part of a promotion.] This is my 3rd APC battery back up. The product is durable, reliable and cost effective. Customer service is a pleasant experience. I recommend this company without reservation.

Easy setup and durable

A replacement for my old one that lasted eight years!!!!

Very Happy

The company I work for is very happy with the surge protectors and we will continue to buy them from you.
