ExpertPower 12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250")/2 Pack

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....

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.

Fitted into my son’s E300 razor scooter. Works well. No issues. Will see how long they will last.

I woke up to a squealing CyberPower CP1500AVRLCD that I purchased in July 2019 so I was not surprised that the SLA batteries needed replacing. I got free same day delivery from Amazon that I ordered at 7:30am and received at 10:25am (5 stars for Amazon Prime!)However, I was disappointed that the ExpertPower box had little protection for the two batteries and Amazon shipped the heavy box in an unpadded envelope. Thankfully the Amazon delivery driver did not toss the item onto my front porch (checked my Nest Video Doorbell).The box was not sealed/taped shut and I see liquid stains on the corners (see photos). Hopefully the batteries work fine and were not damaged (I will update this review if so).First, take pictures as you disassemble the UPS (shame on me). I recommend searching for and watching John Charette's YouTube how-to video for the CP1500AVRLCDa. But I did I take several pictures as I re-assembled the UPS with the replacement batteries. Hopefully they are helpful.

This is a good "form and fit" replacement for the OEM batteries inside the CyberPower LX1500GU model of UPS. I'm very pleased with this purchase. And buying the batteries was MUCH cheaper than buying a whole new UPS unit.Details ...A couple of months ago -- following two brief power outages during the day -- I realized that my CyberPower UPS wasn't immediately supplying power to the connected hardware, even though the display was showing that the battery capacity was 100%. After some troubleshooting (which included me simply unplugging the UPS from the wall outlet), it was easy to see that the batteries were no good. As I was doing a search to find another UPS, I learned that the batteries are replaceable (maybe the original user's manual mentioned that ... but it's been ~3 yrs since I bought the unit). Anyway ...I did a search on eBay and Amazon, and found these batteries. On YouTube there were several helpful videos showing exactly how to remove and replace the batteries -- extremely easy process that only required a Philips head screwdriver and 5 minutes of effort.Bottom Line Results ...After replacing the batteries, I charged up the unit overnight. The next day I performed a quick test by unplugging the UPS from the outlet. Success! There was no loss of power to the plugged in devices, and the UPS periodically "beeped" (as expected) while it was running on battery power. Plugging the unit back into the wall socket stopped the "beeping." Everything worked as expected.

The media could not be loaded. Recently there was a power outage, and my Backup UPS XS1500 (which I found in its original box in a dumpster about five years ago—lucky me!) started making a deafening noise. When I checked it there was an F02 code on the display, which I suspect it was time to replace the battery. I ordered this one, and it arrived the same day. The installation took less than ten minutes. Initially, the new battery displayed only two bars, so I left it to charge overnight. By morning, all the bars were lit up.I then plugged an extension cord into the UPS and connected my routers, main mesh device, indoor and outdoor cameras, and a TV that displays the camera footage into it. To test it out, I turned off the power at the circuit breaker. The UPS ran on battery for 15 minutes, and the display showed another 45 minutes of backup time remaining. I placed a timer next to it, and both the UPS and the timer were perfectly synced.Since I rarely experience power outages, and they usually last only a short time, this setup works great for keeping my internet and cameras operational at all times! Yay! How long it'll last only time will tell.
