Review: Excellent replacement battery - I had a rack mount APC UPS which was about 3 years old. The battery died on me. I bought this as a replacement, and it worked perfectly. The UPS does weekly self tests and they all pass with this battery.
Review: Easy to install - Fit perfectly and very easy to install. I'd buy it again and recommend it. Watch model numbers carefully and you can't go wrong. I watched a YouTube on how to install and that made it even easier.
