SOURCE: In My APC UPS, continuous beep sound is coming

Unfortunately that signals an internal fault with the UPS and it requires immediate replacement / repair. Do not continue to use the UPS at all.

SOURCE: APC Back-UPS ES 500: green light flashes&continuous warning tone

On this unit, the likely culprit is the battery and that it needs to be replaced.

With that, you may want to think about the pros and cons of replacement versus buying an entirely new unit.

This unit is a relatively low end ups and the surge supression uses MOVs that wear out with repeated absorption of energetic spikes. That's why the better (and higher cost) UPSs and surge suppressors don't use them. They're not really that good anyway due to their relatively high transient impedance. The better equipment uses a "transorb" -- basically a back-to-back high voltage zener diode optimized for low breakover impedance and high instantaneous power capability. Unless the transient exceeds the design parameters of the circuit, these do not wear out and do not degrade. That being said, I will assume that you would likely replace this unit with a similar one.
The flashing may not be the battery at all and may be the charging circuitry, thus your new battery may not live very long (half the life that you would expect.

Many batteries out there are refurbs and have issues as all used parts do.

If you contact APC, they will likely give you a 35% discount on purchasing a new product.

The difference in price in the battery replacement vs. ups replacement at this level may only be a few dollars more.

I promise that I am not a UPS salesman, I just deal with many on a daily basis; therefore I am giving my two cents to try to thelp you avoid problems a year from now.

Ok, 3-4 years is a much as you can expect from an ups battery so replacement is indicated. The beeps are letting you know the battery is not able to keep up with demand. So either you have recently added to the system or the battery/s failing.

Verify that the usb to ups cable is pluggled in properly. Also you may not have a good ground. Disconnect the ups and plug it in another outlet to test with nothing else plugged into it, to see if it still beeps. You can also try and upgrade the ups software from apc.com

Apc beeping twice every 2 seconds


The battery inside the APC is "weak", and the "beep" is telling you to replace the battery inside the APC, or, maybe cheaper, to buy a new APC.

ups with 300 watts can only back up 1 computer, though it can handle 2 computers but not too long. your ups battery life span are good only for 2 to 3 years. for battery replacement you can visit the nearest service center and ask for battery replacement. it will not cost you much.

You need to reset the unit to recognize the new battery, I had same problem with one apc smart ups on the bench the other day.

On ours we had to turn off the unit unplug the battery wait 5mins

press the on key and hold for 20secs

reconnect battery

plug in to mains

and start as normal. We did this but still had very low battery time and the flashing lights, so we disconnected the comms interface, that sovled the problem.

It may work for your unit, suggest you check the manual before you try if you are unsure

Hope this helps
Thanks for using FixYa

Strange noise comes out from the ups after a power cut


The Back-UPS Office unit has five different tones or alarms:

This alarm indicates that the Battery Power Supplied outlets are now supplying battery power as opposed to power from the utility. If the UPS determines that the input utility power is unsafe for your computer equipment, the UPS will switch to battery power.
Note: If the power disturbance is brief, you may only hear one or two beeps.

2. Continuous Beeping (On Battery LED will be illuminated)
This alarm indicates that a Low Battery condition has been reached and that the UPS will soon shutdown. Once the UPS transfers to On Battery operation, it can only stay on battery for a limited amount of time. The UPS will sound this alarm about two minutes before the batteries are totally exhausted. Once exhausted, the UPS will shutdown and turn off its output power to your equipment. If you hear this tone you should immediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (Back UPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected an Overload condition after it has performed a self-test during start-up.

4. Continuous Two-Tone Beep
This alarm indicates a severe Overload was detected while the unit was on-battery operation. This tone will continue to sound until the unit shuts down.

5. Continuous Tone (On Battery LED will be flashing)
