### ⭐⭐⭐⭐⭐ 







  
  
    Perfect for a Cyberpower AVR!
  

*by S***4 on Reviewed in the United States on May 18, 2020*

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.

### ⭐⭐⭐⭐⭐ 







  
  
    Tight fit, but it works...
  

*by A***N on Reviewed in the United States on March 3, 2020*

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...

### ⭐⭐ 







  
  
    Good for 3 years but failed structurally.
  

*by E***L on Reviewed in the United States on December 31, 2021*

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.
