BACK-UPS ES 500 started beeping non-stop

that we have to unplug it...totally to make it stop.
Annoying...scary as we did not know where it was coming from at first 2 minutes...
Is there any part of it that i should replace? Or should I throw it?
I am currently using a regular extension (6plugs). Please let me know. I am so confused and upset with this.
I am not a computer savy person and this frustrates me even more.

Thank you for any help.

    Good day Helen,

    I apologize for what had happened. Let me do my best to assist you with the problem. Can you provide the exact model and serial number of your UPS? This can be found on a white barcode sticker underneath the unit. In order for us to properly diagnose the problem, can you tell us if the beeping is accompanied by an LED flashing red or green on the UPS? Can you also tell if the load attached to the turned off when it gave that beep.

    I am having almost exactly the same problem with my Back-UPS ES 500. However it does not beep. It has one sound that is continuous and won't stop until you shut off the unit. It started doing this 1 month ago. I shut it off, let it sit for a day and then plugged it in again. Yesterday it started screaming non-stop again and my roommates unplugged it again. I have 5 other UPS same model and when the battery was dead. They started beeping non-stop. I replaced the batteries and they are still all working? I have had a previous experience with three other UPSes where I purchased batteries for UPSes. The UPSes did not work when the batteries were replaced and once you buy a batttery, if it is not the battery but the UPS, you cannot return the battery. I still have some small batteries kicking around. Does this UPS need to have the battery replaced or do I have to replace the whole UPS.

    Dear JonPro,
    Can you please reply to my thread that I accidentally sent to the previous user? I seem to have a similar problem with my UPS ES-500.

    Good day Angie,

    What I can recommend is to check if the other UPSs that you have are of the same model. If they are using the same batteries, you can hot swap the batteries to see if the constant tone would stop. If you are unsure, you can check the model numbers of the UPSs and post it here and I would check if they do have the same kind of batteries.

    Also, can you tell us if you could see a red or green LED flashing or solid on the UPS while it is producing that constant tone. Are you still getting power from the outlets?

    Hi There,

    The lights were as far as I remember not flashing but solid. Power was still going to the units as the IT guy shut it all down for me and unplugged everything whilst I was not home as they could not stand the noise when they got home from work. But a couple of months ago the computer kept on rebooting itself, which by my research today is an UPS overload symptom. Can't understand though how having only the computer, monitor and speakers plugged in could cause an overload as I unplugged all other items into a power bar plugged into the next outlet. Other units do have the same battery but are located in a different building so can not hot swap. IT guy thinks the unit is toast and I purchased a 750 model today.

    Since you have mentioned that the unit emits a constant tone and we aren't sure if the LED was solid Green or Red. For this particular unit, it is either the UPS has detected a bad battery or a disconnected battery. You are correct as well that the unit is already seven (7) years old.

    I just replaced the battery in my Back-UPS PRO 500 unit a couple of weeks ago and twice it's gone off while the machine was just sitting idle.

    This morning it started a continuous beep and red light was on steady. By the time I was able to get to it to turn it off (less than a minute) the computer had shut down.

    It was fine before the new battery. I have no idea how to diagnose this problem.

    From sticker on back, model # is BP500UC and serial # is NB0114252204. Any advice would be appreciated.

    We have the same issue with "justme7"

    APC Back-UPS ES500 Model  BE500R-PH with serial # 7B1118L08818. At first it will operate as normal but after in a few seconds i can hear twice tick sounds and then a loud nonstop beep sound. We have no other option but to turn it off.

    Actually, we are running chain of fastfood stores and pastries and all branches using you APC Back-ups. Our problem started since our Power Electric Provider supplying us insufficient and fluctuating power. Our concern now: how to fix this problem is it replace the battery (tried already but no luck) or look for the specific circuit component on the board.

    fr0z3nfir3, if you have already replaced the battery and the UPS still shows that sign the unit needs to be replaced.
