ExpertPower 12v 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.

Works fine in Cyber Power 1500VA tower UPS. Hopefully last for a while, but relatively inexpensive as compared to replacing entire UPS.

During a power gray out, my CyberPower CP1500PFCLCD 1500VA uninterruptible power supply (UPS) did not provide backup power, and the batteries had gone bad. The UPS was 3 years old and had the original batteries in it. I replaced them with these ExpertPower 12V 9Ah Sealed Lead Acid Battery pair and testing the unit by removing the power, the UPS works fine and shows I have 90 minutes of backup with the devices I have powered from it.The batteries and connections fit perfect, were easy to replace and operated as expected. As it turns out, only one of the original batteries was bad but since it was 3 years old and about the life expectancy of the lead acid batteries I felt it should have been replaced.

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

Just Works - Used for Residential Elevator UPS Unit - worked perfectly. I've used this brand for gate systems, elevators, etc. and have always been satisfied.

CyberPower UPC 1500VA. Great Value and Excellent Product. This is my second pair of Expert Power Lead Acid Batteries for my CyberPower. The first set lasted 5 years, I thought no way but looked my date of purchase here on Amazon and sure enough April 2020. Easy to install and perfect fit for my CB 1500. They came 100% charged and the longevity of my first pair and excellent capacity and voltage make these a must buy for the price. I run a gaming computer and two monitors with my CP 1500 and these batteries kept up for years. I am a CyberPower and ExpertPower buyer for life....
