APC UPS XS 1500 exploded after installing battery

SOURCE: desk top APC UPS ES750 not communicating

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.

If the issue persists, please visit the following link which lists few troubleshooting steps :

Hello,

With a 980watt load the run time is only 7 minutes on a brand new battery. If you have the system on full load your run time will be much less and it has likely damaged the battery. here is the APC web site page for your model. If you are running that much equipment I think you need either a bigger UPS or another 1500 and spread the load out.

SOURCE: APC back-ups XS 800 battery backup : warning

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
