ExpertPower12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250")/2 Pack

I have a CyberPower 1500VAC Battery Backup that began throwing the E02 error. This error is indicative of the current batteries not holding the appropriate voltage.Upon investigating, these batteries appeared to be direct replacement and so I went for it.These arrived exactly as advertized and were, in fact, exact replacements for the ones I removed from my CyberPower. I tested the voltage of each prior to installation and they were both showing about 14v.Knowing the voltage was good, I quickly got them installed and powered up the device. The batteries arrived with an approximate state of charge around 90%. I have been running these for just over a week without any issues.This was a very simple and straightforward fix with a quality replacement at a fair price.I have chosen to rate this product 5 stars. It has met my expectations for the price and I would completely recommend. Although I haven't had them for very long, I have monitoried them every day and they are holding the charge as expected. Due to my immediate need for the replacement batteries, I didn't spend much time reading previous reviews, but these are definitely worth reviewing. They were exactly what I was looking for and working exactly as advertised.Criteria for Stars:1 - Total rip off, doesn't perform basic advertised functions or not product advertised. I would likely RETURN and would NEVER recommend.2 - Not worth the money. Performs some of the basic advertised functions, but likely not all, and ultimately was deemed as not providing enough value for the money spent. I would not buy again, and would likely not recommend unless the buyer had a very specific use case.3 - It performs the basic functions as advertised, and has some usefulness at the price point, but doesn't work for all of the reasons I purchased. I would likely not buy again, and would only recommend if buyer understood usefulness limitations.4 - It performs most all of the features I purchased it for, but has limitations. I would likely buy again and would recommend.5 - Completely as advertised and likely exceeded expectations. Is if high quality and well shipped. I would totally buy again and recommend.

These were about half the price of the official Tripp Lite battery for my SMART1300LCDT UPS but they are the exact same physical size as the original batteries and seem to work well. Since installing them I've had probably 5 or 6 days with significant brown-outs and 1 multi-hour blackout, with no issues. During the blackout I got about an hour of run-time for my desktop PC. Definitely will consider these again the next time I need to replace UPS batteries!

Batteries in my UPS gave up and I was looking at a new UPS. I realized nothing had changed in the model I had in the 10+ years I’ve had it. Instead of rebuying the same model, l replaced the batteries for a fraction of the cost. That was a few months ago, everything is running great.

My Cyberpower 1500PFCLCD had been great, but eventually the UPS and AVR functionality died. I think the SLAs that came with the UPS lasted about 3 years. I have no idea if CyberPower has an OEM battery option, but batteries are batteries, so there's no reason to pay OEM prices.Though they took a couple weeks to arrive, the ExpertPower 12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250")/2 Pack showed up at my doorstep undamaged and intact. The packaging wasn't extremely protective, but SLAs aren't exactly delicate, either. The 1500PFCLCD comes apart with two small screws. The faceplate slides off, revealing a wire harness and the battery pack. Once you disconnect the wire harness, you can slide out the pack. The "pack" just consists of two batteries with a plastic tray in-between them. The plate has wires that put the pack into series, so it's just a matter of sliding 4 spade connectors onto the F2 battery terminals. You can tape the pack together, but it's not necessary if you hold it together when you slide it back into the UPS. Once you've done that, you just re-attach the wire harness.Really, that's it. My batteries arrived about 90% charged. Nice. I plugged everything in, got everything started, and yanked power. No issues with the UPS at ~85% load. Estimated runtime was close to what I'd calculated for 216 Wh, so the batteries look like they are the right spec. At about $40, the price is good... the only gripe was that the shipping, while advertised as Prime with ~ 1 week delivery, was about double that. Recommended

I have a Cyberpower 1500 that I've had for many years, and it needed new batteries.These batteries came near fully charged. Using a digital meter, they were slightly above 12 volts DC. I wouldn't expect fully charged batteries; batteries have internal resistance, and naturally loose charge. These two were made in February or '24, just 6 months ago. Their dimensions are the same as the original batteries in my UPS. Replacing was simple.1. Unplug the UPS.2. Remove two Phillips screws on the bottom of the front panel.3. Slide front panel downward, then pull forward.4. Unplug two small electrical connectors from the front panel, and the large one from the battery pack.5. Pull on the clear tab attached to the battery pack to facilitate sliding the pack out of the case.6. Remove the clear plastic strips that hold the two batteries and their center connecting piece off.7. Carefully remove the wire connectors in the center piece from the terminal on the battery.Now, revers to install.I used the test feature of the UPS to verify it worked. They passed the test. Good as new. So, I set my UPS parameters in System Preferences-- there's no need for their PowerPanel software ("Hello, I'm a Mac.")-- and I'm up and running again for less than four times the cost of a new UPS.

Purchased these as replacements for my Cyberpower UPSes about a year ago. They seem to provide the run time as advertised and are still testing as good. Replacement was simple and the price was excellent.
