Question about CyberPower 325SL (CPS325SL) UPS System

CyberPower 325SL won't work...

I have a CyberPower 325SL backup system w/ an internal battery and lately it has been plugged into another surge protector and has worked fine. I took it out to use it separately and now it will not work properly. The battery charges and when I plug in/ turn on the surge protector the "Power On" light comes on for about 5 seconds and then the system turns off and starts to make the characteristic long beep. I've tried turning it on and off and also have plugged it into several outlets in the house and the problem seems to be with the surge protector.

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.

That's a tell tale sign of wornout batteries. They last about 3-4 years in a UPS like this. Here's a replacement:

Why is my Cyberpower 550 VA surge protector beeping in set s of 3 beeps every few seconds after a power failure in the house?

This is a battery backup power supply as well. The beeps alert you that you need to power down your equipment before the battery fails.

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.

Why does the 4 outlets (surge only) of my cyberpower 685avr work while the 4 outlets with battery doesn't?

The battery only works when it isn't plugged into the wall. That's what a battery backup is for,so when the power goes out, the battery kicks in.

PR1500 is completely dead. No lights. Pressing reset buttons does nothing. Possible electrical storm hit. Took other equipment out as well.

srogers583, Check to see if external fuse or internal fuse may have gone "open circuit" during a feeder line transient spike. Is PR1500 used in residential or industrial location? If unit was not on a "surge-transient" protected ac feeder line, unit may need to be repaired at CyberPower. 12fixlouie

I have a cyberpower 485VA and after 10 sec it turns off and beaps

It sounds like you need a new battery. The UPS will not turn on if it detects that there is a bad battery. Here's a link to a replacement:

Turned off my system

Well, it did just what it's supposed to do, protect your system from bad power. You probably had a power failure during the thunderstorm and your UPS shut down your PC. When you turn it back on the battery was too low and it shut off you PC again.Check your UPS software in windows, you should have an option to run a self test. But it should be just fine.

The battery plug in area is dead but the surge protector side works

Hello Vicki,

What you are describing is usually a result of the batteries losing their ability to hold a charge.

The surge protector side does not rely on the batteries.

I found good batteries at a reasonable cost on ebay, but I think you're going to need to replace batteries at this point.

Hope this helps.
