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 TownDestroyer, We appreciate your suggestion and review. The SX650U unit is considered to have a non-user replaceable battery per UL guidelines which is why a replacement battery is not listed. If you have any questions, please feel free to reach out to our support team at 877-297-6937 and we'd be happy to assist. CyberPower

Does what it is supposed to do.
Have been using CyberPower backups for many years. A great device to protect sensitive electronics from voltage spikes and intermittent power outages. I live in an area that has a lot of intermittent power outages that last only a few seconds to one minute, just long enough for a voltage spike or long enough to make devices shutdown and have to reboot. Very frustrating when I loose power for 3 seconds and it takes the modem, computer, and cable box 5-8 minutes to reboot. CyberPower backups protect your devices from the spikes plus provide power to keep them running while the power is off. There's enough backup power to save your work and shutdown a computer until the electric comes back on. Check the total combined wattage from the specifications of all devices to be plugged in to be sure the CyberPower backup model will support your devices. This model supports a maximum 360 watts for backup power which is enough for a computer and monitor. CyberPower doesn't recommend that you plug items into this model such as a printer or paper shredder. They sell several larger models that support higher wattage devices. I have a 600 watt model protecting my stereo and TV. The battery in these are customer replaceable, but my 600 watt model has been in use for almost 15 years without a battery failure. This model is working just fine protecting a 16 camera IP security system with monitor. No issues. Stops surges and spikes while providing enough time to save work and safely shutdown sensitive devices. I highly recommend CyberPower UPS's over a standalone surge protector.

Died after 19 months
Purchased in December 2020 and died in July 2022. Battery replacement is almost as much as a new unit. This product is not an economical investment. Next time I will spend more money on a more reliable UPS.
