QuestionHi, can I configure the UPS to be silent instead of sounding an alarm? This would be handy when out of town and living in an apartment/condo.
Asked 4 years ago by MsOutdoorsy.
- Answer Hello MsOutdoorsy, Yes, the unit has a mute button right over the LCD display. The only alarm that cannot be silenced is an overload alarm as that is something you'd want to address right away. Thank you for submitting your question!

QuestionI was wondering if it was pure sine wave when it was plugged in the wall and when it was being operated thru the batttery ?
Asked 5 years ago by Sinewave.
- Answer When the on battery power, the GX1500U will output a pure sine wave. When it is not on battery, the unit simply passes through line power so the quality of power there will vary based on the power provided. Thank you for submitting your question!

QuestionWill this protect electronics from brief brownouts? I haven’t measured the voltage fluctuations I’m getting, but say my 120V drops to 90V for a second or so.. does the voltage regulation bridge the gap and attempt to keep the output at 120V?
Asked 5 years ago by cfarber.
- Answer Cfarber, yes, the voltage regulation does its best to keep the voltage output steady. However, if the voltage drops too low, the system will likely switch over to battery power.

QuestionCan you lay this on it's side? It would not have anything on top of it or put into any enclosure. Just more convenient to be on it's side
Asked 5 years ago by Chipper.
- Answer The UPS can be put onto it's side. If it were to be enclosed, all we recommend is to have 1 inch of breathing room for the vents. Thank you for submitting your question!

QuestionI have 5 nest cameras and the power goes out in big bear alot how long can the back up give power to the cameras ?
Asked 6 years ago by Scooby1962.
- Answer Hello Scooby1962, This is a great question. The runtime is dependent on the total load being placed on the battery. We suggest finding the total wattage being used and referencing the runtime chart on the product page. We've provided a link to the page below.

QuestionCyberpower's website GX1500U spec sheet, what changed? In Marrch 2026 I downloaded 2020 spec version-2 page . In June 2026 revisited and downloaded new 2024 version (not 2026) 3 pages. Note both show 5 ft cord (not 6 ft). But what specs actually CHANGED?
Asked 2 days ago by Chris.
- Answer Hi! Great question, and thanks for taking the time to compare the spec sheets. While the newer (2024) version is longer and more detailed, there were no actual changes to the GX1500U’s hardware or performance. All key specs remain the same, including: 1500VA / 900W capacity 12 outlets (6 battery + 6 surge) Runtime (~11 min half load) Pure sine wave output 5 ft power cord (unchanged) The updated document simply adds more detail, such as USB charging ratings, voltage ranges, and expanded battery information. Hope that helps!

QuestionType of battery and years life of battery?
Asked 3 weeks ago by Swingmeister.
- Answer Thank you for the question. This model uses sealed lead-acid batteries: 2 internal 12V/9Ah batteries. The replacement battery cartridge is CyberPower RB1290X2. Battery life can vary based on use, temperature, and how often the unit switches to battery power, but UPS batteries typically last about 3–5 years under normal conditions. Keeping the unit in a cool, dry location and avoiding frequent deep discharges can help maximize battery life.

Just make sure it's stored in a cool, dry place and periodically charged if unused for several months to maintain battery health.

QuestionI have two Ring cameras that run roughly 4-5 watts each and a modem and router that pull just over 10 watts. In the event of a blackout or if the fuse is tripped, how long will the backup battery last until the power is restored?
Asked 3 years ago by dittmda.
- Answer About 25 hours, most UPS’s give you about 15 minutes at max wattage, so doing the math that gets you roughly 25 hours. This obviously can change based on how much power is being utilized at all times, climate and humidity, efficiency factors, as well as the wear and tear on the UPs unit. Out of the box id expect a guaranteed 20 hours though no matter what.

Asked 4 years ago by mosh.
- Answer Mine says it provides 900 operating watts. I personally have an i7-8700k, an EVGA 3080ti and a ton of RGB fans and I’m requiring as many as ~650 watts so this 1500va/900watts model works fine.
