It sounds like you may need a new battery. The batteries are continuously tested by the UPS and it could be that the voltage is passing one test, and failing the next which is resulting in the light flashing. You can test the battery with a voltmeter. It should read over 11.5 volts, if not you need a new battery set. You can get batteries from http://www.batteryinternational.com/ups-batteries-apc-batteries.html

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.

Hello, I have a APC Backup UPS 800 (5 year old) started beeping. Assumed it was a battery problem and ordered a new APC RBC32 battery. When the battery arrived, installed it to the unit only to see...


Because of the electrical burning it is likely that the battery was not the cause of the issue in the first place, it is also likely that the unit will not be able to be repaired by you personally. Often these batteries have very long warranties and coverage, so see if APC will take the unit back along with the battery, if the battery was used in a faulty machine it may have been damaged so i would return that too to make sure that the problem doesn't come back in the future.

Alternating green and orange light with constant beeps


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

Nope! The internal battery is not plugged-in correctly. Unplug the APC unit and open the access door to the battery (it is not dangerous to do).
Re-seat the two wire clips (red & black) to the battery. The positive post has a red mark on it.
Close it up and charge for a few hours before using.

If the symptoms continue, return unit to store.
