    Our old battery backup finally went bad. We had it for maybe 10 years. I had bought it at Best Buy. So I went back and bought this backup battery.

    I started buying CyberPower after several deceptions with the direct competence. As any CyberPower unit, it does the job perfectly but remember, the batteries, regardless of usage, do not last more than a year or year and a half. The good thing about this units is how easy is to replace the batteries and the cost is inexpensive (compared to the competence).
