CyberPower CPS825AVR trips after 5 seconds

My CyberPower CPS825AVR worked fine for many years. Now when turned on it stays on for about 5 seconds and then trips. I checked the battery it has 13V, looks OK; it is a new one I installed about 18 MO ago. Before it is doing as described above, it was on for about 10sec, then shoot off, came back on again, it was like cycling. While it is on there is power in the 3 battery/surge outlets. There is always power on the 3 surge/only outlets, when plugged in.Can anybody please tell me what to do to fix this problem?

Needs a new batter most likely. The same thing happened to my CPS825AVR that I use in my home office. Emails to CyberPower went unanswered so I had to solve it on my own. It uses a lead acid battery much like those used in emergency lighting, and not unlike a battery in your car. It will initially fail to keep your electronics on after a power failure, just shutting off and beeping like mad. Then it will fail to stay on entirely. Try holding down the red reset button for a period of time. It may reset, but chances are it will not work after you unplug it from the wall to simulate a power outage, and will need to be reset again.

For me the first failure occurred when the unit was left in storage. Like most batteries a lead acid battery if left uncharged will deteriorate and be unable to hold a charge. The second battery purchased online just failed after barely more than one year. It was a battery made by Werker, which is a very common replacement battery for emergency lighting also. At this point I am not going to spend any more money in this unit. It is unclear to me as to whether it is a lousy battery or the unit is unable to maintain a charge in such a way that the battery will survive a long life.

I will buy a UPS made by APC, I am using an APC for my entertainment system now. They are more readily supported and offer more options with regard to replacement batteries. I suggest finding a model to suit your needs and then search to see what support there is for it. I got about 5 years out of the first battery and was able to easily get a replacement online. The APC batteries are also relatively competitive in pricing so there is less need to pursue an aftermarket brand.

Can I purchase replacement battery for the CyberPower 825AVR? and if so how much is it with shipping? I'm in upstate NY


keymast, if you can open your 825avr unit take picture before disconnecting battery. then find local car/truck battery retailer locally that also deals with SLA batteries for alarm systems and emergency lighting systems. They should be able to source an exact replacement for you. Or else search the web using the search term "sla batteries" or "sealed lead-acid batteries" . You will get plenty of hits on web. 12fixlouie

My computer won't boot and the CyberPower 825 AVR makes a continuous sound.


It sounds as though the UPS is not receiving power. Check that it's cable is properly plugged into the wall. Also verify that it's internal ground fault interrupter has not tripped, it's usually a little red button on the back of the unit, it should be pressed in and should stay that way, if it pops out then there is a problem with the ground of your electrical outlet. Also check that the breaker for that electrical has not tripped at your fuse box.

Since the UPS is not receiving power the batteries have discharged and that is why your computer cannot start, there is not enough juice from the UPS to boot it. That is also why it is making a noise as most UPS's sound an alarm to indicate that they are not connected to power.

There is a chance that the batteries in your UPS have gone bad or that something has become faulty in your UPS. Try plugging your computer and monitor directly to the wall bypassing the UPS to see if they work fine.
