NPP HR1221W (F2, 2 Pcs) 12Volt 126Watts,21Watts/ Cell, 12V 5Ah High Rate UPS Battery Replace 12V 5Ah, 12V 5.5Ah Sealed Lead Acid Rechargeable Battery

I got 2 of these to replace my 7yr old batteries in my Cyberpower 1500AVR, and upped the batteries from their original 7Ah to these 9Ah, with great results. I tested by running my pc on battery (with monitor and speakers) for about 49 minutes perfectly!Note: prior to this the UPS would not power on. The display was only clicking on and off rapidly. I was because the voltage of the batteries had dropped to low (measured at 9.89v), so they had just lived their life and needed to replace.

3-2-2020, Revision A:Cyberpower CP1500PFCLCD (Same as, CP1500AVRLCD, battery wise). IT TAKES TWO BATTERIES!!!When using these batteries, make sure you stick them tightly together, before adding the tape. These batteries fit very tightly (provided tape will peel), while inserting battery pack (make sure wires are not pinched between batteries and UPS battery well, wiggle till it fits (the batteries, not you).Battery use, So far so good...

Purchased 4 of these batteries in November 2018 for my Cyberpower UPC and all 4 have failed as of November 2021with the sides of the battery cracking on all 4. Never seen a battery fail like that on one battery let alone all 4. Ordered a different brand to replace those 4.

Ordered 3 of these to replace the batteries in our PC battery backup systems. Much cheaper to replace batteries than to buy new backup systems. I did a battery load test at 100% good. Very happy. They also came packed very well. Thank you

I’ve been using this battery for powering a fish finder on my kayak this summer, and it’s a holds a charge for a long time, granted it doesn’t have much of an amp draw. I’m very pleased with it at this time. Updated review 4/19 Last summer I added a kayak trolling motor to this battery along with the fish finder and it’s still holding out on a half day fishing.

I bought one of these batteries to test boat circuits and stereos etc. I actually started my neighbors Honda Civic with it. A top notch battery . I will buy again. Also the company is awesome.

Installed battery & UPS normal operation has been restored. Battery compartment in CyberPower 825AVR is very tight so needle nose pliers come in handy when connecting terminals.

No date codes! Was disappointed when I opened the package to see this. I hope the company honors its warranty! Will update if anything happens
