UPSBatteryCenter Compatible for BB CPS5.5-12 12V Battery

This model battery is really difficult to find, probably because cyber power wants the customer just to buy a new UPS, so I was happy to find this one and decided to give it a try. Battery looks and feels identical to the original and actually seems to be better quality. So far, it's been working very well and has even saved my computer from shutting down unexpectedly, at least a few times during some heavy rain/wind storms. It was easy to install. Just shut down your computer, hold the power button on the UPS until it shuts off, unplug the UPS, flip it. Then you just unscrew the back cover (phillips screw). Old battery slides out and you disconnect the terminals. New battery fit perfectly in the space. The only issue I had was that while the right physically sized battery was sent, one of the terminals was smaller, when I needed them to be both the larger size. I contacted the seller and they got back to me within minutes and said they'd get an adapter right out to me, so it was clearly an honest error and they went out of their way to make it right. Battery has been working perfectly with the adapter and I'd definitely order from UPSBatteryCenter again! Their customer service really has been among the best I've had on amazon, so on that alone, I'm glad I took a chance. I have found that pretty much all UPS batteries are made by the same companies anyway and just have a label on them that say something like "Cyberpower" or "APC". This company may even make their own batteries and they seem to really care about making the best possible. That’s not something you see with most companies anymore. I almost forgot, while the estimated shipping said it could take a week to receive, it only took a couple of days. Battery was packaged nicely in a sturdy box and dense, non-static conducting foam. So even had the carrier been rough with the package, it'd have arrived in great shape anyway. All in all, really great experience and I only have great things to say. If there were any issues, I certainly would have indicated so, because a big reason to leave a review is to make sure other customers get what they expect and avoid things that are not good products. Great battery, great company, and amazing customer service, what more could I ask?

I bought this battery to replace the one going bad in my Cyberpower SX650U UPS. Like others have mentioned it seems that it is hard to find an exact replacement, but this one fit perfectly and has an extra Ah compared to the OEM. This one fit right in and provides power when unplugged with no issues.

UPS battery center products are great and always fits and outlasts the originals my Older UPS equipment is still working great top quality products

This battery fit perfectly. I measured the old battery's dimensions and compared them to the dimensions listed on the website to make sure the battery would fit. Thanks to whoever that put the information on the listing. There has not been a power outage since I installed the new battery, but it will be there if needed. The computer, modem boxes and the monitor are plugged into the four battery supported outlets. A new battery usually lasts about 40 minutes before it cuts off. When the beeping becomes steady, it is time to shut down the computer. I knew a new battery was needed when the old one only lasted around 10 minutes when the power went out. There is another unit with the living room TV, streaming device, DVD player, and clock plugged into the battery supported outlets. Sometimes I have time to finish watching a show or movie before I have to cut off the TV.

good quality so far - bought a few of these over the years - prices started creeping up recently.

I received the battery quite promptly and had my internet/tv power back up system up an running again in minutes. system is working as good as it did when I got it several years ago, Thanks

My battery went dead and I needed a replacement fast. Amazon delivered the next day, and I was up backing working. The product was exactly what I ordered, and easy to plug in and go.

It works great
