Unable to stay powered on

I have just replaced the battery in this ups (full charge at 12.7VDC) and after initial power on of the unit, 4 sec later it clicks to yellow and shuts off, all fuses and breakers check out and I am unsure if its a relay failure or IC system problem.

How often should a laptop battery be replaced?


Depends on how the battery has been cycled. If you charge it for 8hrs or until its full and you stay on it until it's discharged all the time. It will burn it up fast. Also if you charge it and then use it while its on the charger and hardly ever take it off, that battery will eventually learn that cycle and it wont last 4 hours. It's best to fully charge it and have an extra as you can switch between the two around 25% battery left. I would replace it and start fresh. You can also turn off all applications that are running in the background as they will eat alot of power.

follow this steps and fix it. God bless you
Plug the battery backup into a working electrical outlet. If the battery backup turns on when the power button is pressed, then the problem may be that the previous electrical outlet is faulty. Proceed to step three. If the battery backup doesn't turn on, proceed to step two.
  • 2 Reset the circuit breaker on the battery backup. APC battery backups have a labeled circuit breaker button located on the unit near the phone line, fax line, USB, network and coaxial cable inputs. Press the button to reset the circuit breaker. Power on the battery backup by pressing the power button. If the battery backup powers on, proceed to step three. If the battery backup doesn't turn on, proceed to step six.

  • 3 Determine if the battery backup is charged and providing battery power. With the battery backup on and plugged into a working electrical outlet, plug a computer monitor into one of the battery backup outlets labeled "battery backup plus surge protection" on the battery backup. (APC power supplies have some outlets that provide only surge protection while the other outlets provide surge protection plus battery backup.) Turn the monitor on. Unplug the battery backup power cord from the wall outlet. If the monitor remains on, the battery is holding a charge, supplying electrical power and the battery backup is working properly. If the monitor goes off, proceed to step four.
  • 4 Charge the battery. Plug the battery backup into an electrical outlet and allow the battery to charge for 16 hours. This will fully charge the battery.
  • 5 Test battery charge. Once the battery is fully charged, repeat step three. If the monitor stays on when power is interrupted to the battery backup, the issue is solved and the problem resulted from an incompletely charged battery. If the monitor turns off when power is interrupted, the battery within the battery backup is faulty and needs to be replaced.
  • 6 Replace the battery backup unit. The unit itself is faulty. If the battery backup is under warranty, contact APC to request a replacement.

    Backup power ends quickly even with new battery


    What is the load on the unit? How old is it?

    The symptom can occur if the load is too large. It will also happen when the unit reaches a certain age.

    I've found that the low-end consumer UPS's should be replaced when the battery fails. The charging circuitry usually fails to charge the battery even with a new battery soon after the replacement.

    The way I check if the battery or the UPS charging system has failed is with a voltmeter to give the current voltage and a variable DC power supply (whatever is appropriate for the battery) to attempt to charge the battery. I can watch the battery discharge with an oscilliscope if I want a full trace of the unit.) Charge the battery fully then watch the unit over time. If the battery itself is bad, you won't get the full charge or it will discharge as soon as it is removed from the power supply.

    I hope this helps.

    Hello sir, I don't actually know how to charge my apc cs 650... and And when the power is out, so does my computer.. low battery.. I just need a simple answer about this.. is it not charging? or do i need...


    If you connect the control cable to a PC and install the PowerChute Personal Edition V3.0.2 f software you should be able to see if it is charging and what the percentage of charge held in the battery is.

    On the CS 650 the lowest power connection is the surge only powerpoint.

    To give the battery a full charge or to test it you can connect it to a car battery trickle charger, as it is a 12 volt battery, rthis will at least mean you can check that it holds a charge in the first place.

    CyberPower CPS825AVR trips after 5 seconds


    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.

    Tripp Lite OMNI 1000 LCD will not stay on


    Turn UPS on: Press and hold the ON/OFF button for one second.
    Run a Self-Test: Press and hold the MUTE/TEST button for two seconds (until alarm beeps several times).
    The test will last 10 seconds. All LCD Display icons will be illuminated and the alarm will sound.
    If the fault icon remains lit, the battery-supplied outlets are overloaded. Unplug powered devices until you remove the overload.
    If the "Replace" icon remains lit and alarm continues to sound, the UPS batteries need to be recharged or replaced. Allow UPS to charge for 24 hours and repeat self-test.

    Supply problem with Smart UPS 700


    Above shows that you are trying to Cold Start the UPS. That is only used when there is no utility power. It is running everything off the battery only. Try charging the battery again and this time try just pushing the ON button and releasing.
