Here is an answer I got from APC when one of my client got the same problem as you did:
The error message would pop up if the link between the computer and the UPS is weak. I cannot rule out a problem with the cable or the UPS. In order to confirm the same please try the following steps which might help :
1) Ensure that the USB cable is properly connected to the USB port of the computer.
2) If the PC was powered on before the UPS, communication will not be achieved until you disconnect and reconnect the USB cable to the host. In this case, you need to disconnect and reconnect the USB cable to establish communication.
3) Some other software is polling your USB port for another device, thus causing the UPS software to temporarily lose communication with your UPS. If this is the case, you would need to shut down that application.
4) If you have any other USB devices connected to the PC, disconnect them and then try plugging in the cable.

i think by replacing the battery has not been the solution to the problem
u need to check the battery charging voltage when turned ON with main electricity, if no voltage present from charger, there is no question of battery getting charged and also once the battery is down with charge it may not re charge hence the indicator and alarm.
recomended to nearest service centre

it seems that the inverter circuit of your UPS is dying. the solution here is you have to open up the UPS and check the inverter circuit. to make easier, check the power mosfet if its leaking.

Turn it off and unplug it from the wall.
Open it up and make sure that the red and black wires are connected.
If they are the battery needs to be replaced. They are only good for 2-3 years. If you are not comfortable with my instructions, call APC for free support. (800) 555-2725
Vote for this solution if it helps.

I've seen where the software can hold on to past readings and give erroneous alarms. Try uninstalling the software and reinstalling if all else fails.
As a last resort, try disassembling the battery pack and checking the voltage of each battery. Each should read 13 vDC (+/- .5v). There are several batteries in this pack so one bad battery can pull down the whole string.
