    I bought the unit to keep my small system “alive” in case i lost power The system has Alarm Clock HQ and is critical to my current hobby.Being retired the loss of the data would be a major blow About 4 days after I bought the unit I lost power and thanks to the battery backup everything kept going.

    I chose to replace my old CyberPower backup with the same capacity and brand when the battery died. Rather than go through the hassle of ordering a replacement battery for the old one, I found it more convenient to buy a new unit. I have been buying the CyberPower backups for some time, and am very satisfied with them.
