    This one replaces my last one that lasted about 8 years. The battery ran out and it was the same price to just replace the unit. It has never failed me.

    I'm using this to mainly supply power to routers and a switch in the event of a power outage. It's replacing one (same manufacturer) that last about 10 years. I'm hoping for the same performance with this on.

    Much lower price than the factory branded battery. Appears to be well made and I believe that it will last as long as the factory branded one.

    Works as advertised. Four plugs on battery power. Four plugs that are surge protection only. The CyberPower software works well with Windows 10.
