    Plug Play Run
  

*by R***E on Reviewed in the United States on September 26, 2022*

Replaced the battery in my ups with this, as the old one had my UPS screaming that it was shot. New one shut that alarm down.

### ⭐⭐⭐⭐⭐ 







  
  
    Seems to be a good replacement battery and a good value.

It appears to work well as a replacement for my battery back-up.  No way to tell how long it will last - time will tell!
