Alternating green and orange light with constant beeps

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.

Hi Lasantha,

Check the battery in your UPS - it's most likely going bad and you will need to replace it.

If you need UPS, Surge, or Power Related help contact Daniel @ Power & Systems Innovations 800.260.2259 or go to our website: http://psihq.com/

the apc ups performs a self test when ever it is powered on.... it should complete the process in 10 to 20 second but if it does not, then there is something wrong with ups.. try to get it checked...

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.

change the battery

A blinking green light is likely an indication that the internal battery is nearing the end of its usable life cycle. If it's over 3 years old this is likely the case. To test, plug something in to the battery outlets and pull the plug of the UPS from the wall. If you get a short runtime (or none at all) it's the battery. Batteries are under $20 and can be found here: http://www.batteryinternational.com/apc-backups-es-be350u-ups-battery-ups-batteries-f1.html

It sounds like you need a new battery. If the APC is more than 3 years old, that is likely the problem. You can get a new battery from http://www.batteryinternational.com/apc-backups-es-be500u-ups-battery-ups-batteries-f2.html

I would recommend replacing APC UPSs with ONEAC ONEPlus Power Conditioned UPSs, which have a perfect ground reference, longer lasting and more reliable batteries, and a 5 Year Warranty (2 Yrs on Batteries).

1) Switch Off the UPS and unplug all Loads (like System, Monitor etc.) from UPS.
2) Switch Off the AC Power (Input Power to UPS).
3) Press the UPS Power Switch constantly unless you hear 2nd BEEP Tone. As soon as you are hearing 2nd BEEP Tone, Release the Power Switch.
4) This is COLD START of all APC UPS that will reset any internal problem.
5) If, however, the problem persists, contact APC.

I have my apc beeping all time with and with out battery,I need a solution. Thank..oscar
