Gordon F.: I watched a youtube video before installing these new batteries for my CyberPower backup battery. It was verfy helpful and made the battery removal and replacement much easier. The battery came fully charged and works perfectly.

Christopher Gray: Seems to work ok. Just completed replacing the two batteries in my CyberPower CP900AVR. The Issue is that the power terminal leads are two wide. I had to trim them in order for the wiring harness to proper attach. Hopefully they stay attached and I do not have issues due to poor connection.

b: I just received my third set of these batteries. I am averaging less than 18 months on a set of batteries. I only know this because a shipping issue that caused me to look at my history. With this life span, I will be looking for a different solution in about 18 months.

Ken from the Olympic Peninsula: The batteries seem to be a direct replacement for the original CP900AVR batteries. Replacement is straightforward, removing the long screws from the base and lifting the top off, noting the existing connections, replicating those with the new batteries and closing it up. My only snag was not accounting for the separate power button extender (the red plastic button that protrudes above the case) when replacing the cover and having to open up the case a second time to fish it out and correctly place it before buttoning up. The batteries charged up within an hour or so and though I haven't had a genuine outage since replacement, everything functioned correctly when I unplugged the unit under the load.
Shipping packaging was a bit shoddy, with an inner manufactures package nestled inside a mailing box with a handful of Styrofoam peanuts, which left the inevitable pile of statically charged Styrofoam particles clinging to everything (especially me!)
