Why does unit turn on and off repeatedly


The batteries need to be charged regularly.
If the UPS starts more often than before, perhaps the batteries are bad and do not keep their charge.

Battery Back-Up not coming back on after power outage. Charged for several days without anything plugged in with trip button pushed in. Surge side still working. No beep light or anything on battery...


Does the unit have a breaker on the back? There may also be a fuse. You should be able to find a users guide on the CyberPower website.

If the unit may have failed during the power outage.

If the battery is dead, but the charging system is working will that stop the Battery/Surge side from working?


If you still have your dead battery connected it will work as long as there's no power loss, there are rare cases this won't happen, you can replace the damaged one for a motorcycle one or even a car battery as long as they're 12 volts and polarity setup is right, inverse polarity will kill the UPS so be careful.

I have a CyberPower 725SL UPS. Shortly after turning it on, it will beep as if AC power was lost and the green light goes out. I checked the battery and it's good. I'm assuming something went bad with...


Couple different items to check.
  • Try letting the unit set ideal for overnight charging the battery. Do not even turn the unit on.
  • Replace the battery.
If you turn the unit on when the battery is plugged in and does not keep a charge you can almost be sure it is the battery or the charging circuit not maintaining the battery.

Power light is out. Is the unit dead?


Atypically if this is an older unit what you have is an issue with the battery. It will no longer hold a charge.

You will nee d to go to the vendor site and look for a replacement battery.

In some cases it may be less headache and cost just to buy a new one.

CyberPower 325SL won't work...


NEVER mix surge protectors and UPS!!!. Doing so overloads whoever of the two gets connected to the wall. This equipment is built to be plugged DIRECTLY to the wall. Your unit just crossed it's inner battery. Take it to a recycling center, then stop on your favorite electronis shop and buy a new one.
