## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    APC fine but old battery disposal policy not what it seems.
  

*by M***Y on Reviewed in the United States 🇺🇸 on June 1, 2011*

Battery received quickly and installation is really quick and easy. HOWEVER, be aware that while APC mentions inclusion of of free, environmentally sound, disposal method for old battery this consists solely of a few written instructions re: how to take to your local community disposal site in the same package in which the new battery was delivered to you. So it provides no advantage over buying cheaper, non APC replacement battery.  IS THERE A DIFFERENCE IN BATTERY LIFE OVER OTHER BRANDS?  Only time will tell.

    Rock Solid Battery
  

*by M***X on Reviewed in the United States 🇺🇸 on November 17, 2010*

This is a replacement battery for my UPS.  Works very well.  One thing that I did not know is that it came with a shipping box and an UPS label for return of defective battery.  I liked that idea very much because I was wondering what to do with the old battery.May 2015: bumped up the review because it is almost 5 years and it is still working.  Have not stressed test to see how much capacity it still has, but know my model of UPS will not work with a bad battery.

### ⭐⭐⭐⭐ 







  
  
    Slightly incorrect image and specs.
  

*by A***K on Reviewed in the United States 🇺🇸 on March 19, 2013*

I received a different brand and amps (5.1 not 5.5 as mentioned in the description), but otherwise it's working fine.Be aware substitution likely upon ordering.
