CyberPower RB0690X2 UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 6V/8Ah, Black

Perfect fit. Works as advertised

I'm really glad I purchased these. They work great!

I enjoy an "easy" install UPS battery, but this fell a little short. I made it work, safely-ish, and it's hooked up. The issue I had was how short the black wire is. I had to mess with it for a while to make a proper connection. I used two pliers to hold and make the connection with.

Seems to work without issue. Designed for my UPS and solved issue of dead battery. A lot cheaper than replacing complete UPS unit

Easy install, works as expected

Final update:The replacement battery CP sent me won't take a charge. Upon closer inspection, the manufacturing date printed on the battery is 2017. Looks like they keep a pile of old inventory for warranty claims, and now I have to recycle 2 sets of non-working batteries. Thanks, CyberPower.Moreover, this battery is clearly sold as a 9Ah battery. Remove the battery from the tray or peel back the big white sticker ("CyberPower tested and approved!") to reveal the original battery specs - which clearly state you're getting an 8Ah battery.Do yourself a favor and buy a better battery at a cheaper price from a company that doesn't lie about the specs.I'm done with CyberPower.18-month update:The batteries have gone from nearly unusable to complete paperweight: The UPS starts shutting down after less than 2 minutes, with only 25% load.But there's good news: CyberPower stands by their product and honors the warranty. After contacting them by email and describing the issues (right around the very end of the 18-month warranty), they've sent a replacement with no fuss. The replacement batteries are not CyberPower branded and are a 8AH rather than 9AH model - perhaps they switched their battery supplier? I would've preferred the 9AH I was paying for, but if the new batteries hold up, I'll be a happy CyberPower customer again.1-Year update:The batteries have become nearly unusable after just over a year. Fully charged and with less than 25% load, the UPS claims a 30+ minute runtime. The other day power went out... after about 15 mins, the remaining time started fluctuating wildly, and in short order the UPS shut down (while systems were still busy shutting down).This was bad enough, but it got worse: The UPS decided to power back on! ... For about 30 more seconds. And then, with everything in the process of rebooting, it shut down again, this time for good.This of course completely defies the point of having a UPS in the first place. Shame on Cyberpower for selling this crap! (Never had these problems with the batteries originally installed in the unit, and they lasted many years before showing signs of age.)Original review:Installed in a CyberPower OR700, running at ~17% load, these should provide 40 minutes runtime per CPS's runtime chart. I only get 30 with new battery installed and fully charged; the UPS's runtime estimate is originally 45 minutes, but drops increasingly rapidly as the battery depletes, with a drop from 30% to 10% capacity in only 3 minutes. The UPS's self-test status is "Done and warning", whatever that means.So, they work... but not to spec, which is disappointing given that I splurged on the brand name replacement.Replacement is hot-swap, which is nice.

easy to install, works like a champ.

I slipped in this new set of batteries on the tray it comes with. Plugged in and immediately working. Was already fully charged as well.
