CyberPower RB1270X2A UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/7Ah,Black, 2.75 x 7.08 x 4.17 inches

The original battery for my CyberPower UPS had reached its end of life and I needed a reliable replacement. This is exactly what I needed, and installation was simple. It's working reliably now, and since it's CyberPower branded, I have peace of mind that it will perform as reliably over its life cycle as the original battery did.

Every time the power flickers here in FL I love my UPS a tiny bit more. Recently; however, my ups started to cut power to my PC. Knowing that the UPS routinely conditions the battery by charging and discharging I figured that a dead battery could cause these symptoms. Life expectancy ranges of 3-4 years for the battery by the company strengthened my suspicion that the almost 5 year old UPS was just needing a replacement.The package came with instructions to access and replace the battery for a bunch of different models, including mine and the process was straight forward. For my unit it took two screws and removing/replacing a few slip on wire connectors. It took a second to get the battery all the way back in to it's compartment before screwing the cover back on, but it wasn't very difficult. UPS is back to working great with a complete end to the regular power loss I was experiencing and once again keeps the PC running when the power goes out.My biggest takeaway from this for me is that a UPS designed to keep power stable can actually have the opposite effect when the battery gets to the end of it's life.

The Cyberpower I put this battery into is now on it's third set. I had tried an off-brand last time, seemed to work OK but for the small difference in price I found this time around, I just bought this instead. Fit right in, easy to do, and 1/3 the cost of a new UPS.

This replacement battery fixed my CyberPower UPS, which would turn off by itself when self-testing.I recommend this replacement battery since it solved the issue and completed its self-test successfully.

My ups batteries were shot so I bought replacements. They fit like they should and the power just went out and my UPS kept everything up until it came back on.

I have a CP1350PFCLCD (according to the model # listed on the product itself) and this battery DOES NOT fit it. You need to get the RB1270c 12v/7A batteries instead, and you'll need two of them.

Still contains a pair of BB Battery CPS7-12 7AH batteries. Most other batteries in this form factor are 5 or 5.5AH.Installation is reasonably simple; there are two screws under the front panel; the front panel pulls away and the batteries can be accessed. Sometimes the old batteries swell and need a bit of persuasion to be removed.These are about 30% to 50% more expensive after considering shipping than the generic lower AH alternatives. They also have 40% more AH. Thus the price isn't awful considering they last 3-5 years.The 1350PFCLCD seems to have a poor battery test. I've had two sets of batteries fail in the last 8 years and neither time the "change battery" light came on. Instead, it simply dropped dead from the slightest power glitch. Replacing the batteries restores normal functionality.

Does not seem durable or good value for money. Worked fine for a couple of months. Unit just ticks now and the battery seems to be dead. Now we have a heavy surge protector. Will think twice before replacing batteries again.Our power dips a lot, however is this not what was designed for? Unit worked just fine for years until the initial battery was dead.Happy if it works great for other people. Not our experience.
