New apc xs 1300 only puts out 100 volts when disconnected from power supply of 119volts.

Battery is fully charged and shows at least 60 minute duration.

Serial # 4B1329P23746.

Fans slow down when on battery backup.  This can't be good for the electronics.

Have tried unit reset as mentioned in another post.  Unit unplugged, battery removed, power button held >20 seconds, battery replaced, unit plugged back in to power.  No change in output, still 100 volts as tested with multimeter.

Is the voltage output adjustable?  Any suggestions?

Thanks
