it might be overloaded or there may be frequent voltage flutuations.
try connecting only the pc without connecting any peripherals and accessories like printers...
if possible use a voltmeter/multimeter to take voltage readings...
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
There's no single or simple answer for how long the battery will last. If it's in a place where the temperature is fairly stable and it's not called on for backup power very often, it may last 5-6 years. If it's in a place that runs hot and cold and/or goes through a lot of discharge/charge cycles, then it may die in as little as a year.
The 825AVR has a fairly common type and size of sealed lead-acid battery. Search the web for "HR1234W" and find your price.
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.
