    It's a great price for the Mighty Max backup battery, and fast shipping time to me as well for no charge. I knew I would have to cut out a bit of my CyberPower 'receptacle' box to accommodate this model, but it is deeper than expected so have it mounted to the wall without the back cover on it. This is a minor issue compared to the great product, great price and service.

    I was excited to get the battery, but it was an inch too long and didnt fit the 425VA unit. Needed to verify the length. I'm not sure how to return it to get the correct one. Jeff Pollnow 501-288-3988

  • Close enough

    I have a different Cyber unit, but with some pliers ripping out a bit of plastic, she fits. Much better deal than $50. 12V is 12V, larger battery means more Amp Hours.
