Question about CyberPower 825AVR (cps825avr-sc) UPS System
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.
