It would be nice if CyberPower told customers what battery this UPS uses under the product overview because replacement batteries for this unit are not sold in store at Home Depot or on the homedepot.com website therefore I am deducting on star. A replacement battery will cost around $37 which is about 75% the cost of a new UPS. If one needs an immediate replacement battery, he may have to take a 25% loss and just buy a new UPS in store.

Hello Bob, This unit does not have transformer spaced plugs but we do have other units with that feature. Please reach out to the Cyber Power Sales team at 877-297-6937 if you'd like assistance with product selection. CyberPower
Not Bad
This Cyberpower unit adequately kept electricity flowing to my modem and routers during a series of recent power outages in rural Connecticut. It replaced a two-year-old APC unit whose battery failed prematurely. This unit has design limitations, however. One limitation is that the spacing of the outlets does not adequately permit enough transformer-type plugs commonly found on small electronics. Another limitation is the lack of a mute button on the power outage alarm; unlike new units, this one will scream at you incessantly when the power goes out for the duration of its battery backup with no option to mute the alarm. For a few dollars more, I recommend considering one of the newer units with a better outlet layout and a mute button.

Hello, Thank you for submitting your review. The SX650U is a compact device with no transformer spaced outlets. We do have larger units that do accommodate for transformer plugs. While the unit does not have a dedicated mute button, it can be muted by pressing the power button 2 times, quickly. If you need assistance with product selection or info on the unit, please reach out to our team at 877-297-6937. We are always here to help. CyberPower
