I have the same problem with an apc smart-ups VS 650.

 

New batteries - charge in batteries is good (also tested under load).

 

When AC power fails, no power is supplied to PC connectors by the UPS.

 

UPS self test works fine. UPS does not report any problems via software - Power Management under Windows XP.

Yes there are replaceable batteries but if yours is only 6 months old and was new this should not be the problem. That said, batteries only have a certain lifespan from the date of manufacture. If it sat on a shelf for a long time before it was sold the battery could be junk.

Is the tone continuous? If so this is the overload alarm.

APC passes its self test but no backup
More than likely it is the battery. These units simply test the voltage during the self test, and, although not typical, the battery voltage could be good without a load, but fail with a load. 3 years is generally the life span of SLA batteries. Replacement batteries are fairly inexpensive and can be found at: http://batteryinternational.com/ups-batteries-apc-batteries.html

APC Back-UPS ES 350 - when powered on has a blinking green light Is this normal
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

Green light flashes with a constant buzzing sound but it still powers other equipment? Do i need to replace the battery on the APC UPS-ES 500
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

APC external Backup battery is not working plz
It may just need a new battery. The UPS will do a self test on the battery when you turn it on. It may have tried to read the battery and the result came back as "failed". The batteries last about 3-5 years, even less if you live in an area with bad power. The batteries are very easy to change. You can buy replacements at www.batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

APC Smart UPS 1500 will not start.
It could be that the cable to the front-panel got damaged during the battery replacement.  After all these years you would think APC would improve that aspect of their design.  All I can suggest is inspecting the cable and where it connects to the front panel.

Less back up time
I found the following on APC's web-site for the APC Back-UPS, this will hopefully fix the problem:
You can also perform a manual runtime calibration. This could be done if you have changed your equipment load or battery. Stop the PowerChute software from running; disconnect the serial cable between the computer and UPS. Next unplug the UPS from the wall and let it run on battery until it reaches low battery. Once it reaches low battery plug it back into the wall outlet and let it recharge. Recharge time can take up to 4 hours.
