I like that it protects everything I have running including my router too. My computer would shut down when I printed something due to my network printer. I have the computer in the battery side and my computer does not shut down anymore. I feel like I am protected better than I have ever been before!

- Great packaging, fast delivery.

This solved a dirty power issue for an industrial control panel I service frequently.

Got here in 2 days. Put it in and it is working well so far. Got 7 years of continuous use of the one it replaced. Hope to get at least this long with these new batteries. Came in at 85% charged. After plugged for an hour it went to 100%. So, no issues.

Length: it's shorter than others so it will mount fine in 2 post racks using included heavy-duty mounting brackets. Price: excellent value for your dollar. Tons of features you would not expect for a device under $1000. Quiet: does not make a horrible racket like other UPS in its class. Just a periodic chirp and light fan sound. Powerful: 20A means you can put more load on it and it will charge faster.


The CyberPower RB1290 UPS replacement battery was easy to install and setup on my CP1000AVRLCD.

This UPS was a great solution to support networking equipment (modem, router, switch) that I installed in my basement. It has lots of outlets and the size of the unit was perfect for mounting on the network wall panel.
