    Didn't last
  

*by S***Y on Reviewed in the United States on September 25, 2021*

I bought and installed this battery, tested it and it worked fine, I had a short 3 minute power outage about 6 week after the install and it still worked. The next power outage was just after the one year warranty was up and the battery was completely dead while the original battery lasted nearly 6 years and gave me the fault beeps when it started to fail. I'm going to try something different.

### ⭐⭐⭐⭐⭐ 







  
  
    Service life almost 32 months
  

*by A***S on Reviewed in the United States on October 13, 2020*

I installed this battery as a replacement into an APC CS 500 Back-UPS on Feb. 20, 2018.  When I came into the office on Oct. 12, 2020, the unit was squealing and in fact would not stop until I unplugged the unit and removed the battery completely.  The manufacturer indicates that this battery has a "long life."  I would have expect perhaps another six months to one year of longevity, but for the price still can't overly complain about the battery's service life.  The APC unit was plugged in continuously to protect a PC that was minimally used during this period, perhaps three for four hours per day for no more than four days per week.

### ⭐⭐⭐⭐⭐ 







  
  
    Works as good as original.
  

*by R***Y on Reviewed in the United States on July 2, 2018*

Bought this battery for a CyberPower 685AVR. Battery came on time and package very well. Took the old out and inserted the new one with 0 problems. Left all recepticals unplugged and plugged in Backup to charge overnight.. plugged in my computer and router, etc the following day and had an outage shortly after and the backup with new battery worked flawlessly.
