When the battery is low, or dead, on these it will act this way. You may want to try a new battery. Here's a supplier: http://www.batteryinternational.com/cyber-power-cps725sl-ups-battery-ups-batteries-f1.html

The batteries are very easy to replace on this model. You can simply remove 6 phillip head screws in the bottom and the unit will come apart to reveal the battery. Simple fast-on connectors. Here's a link to a new battery for that model: http://www.batteryinternational.com/cyber-power-cps725sl-ups-battery-ups-batteries-f1.html

Tom, usually those can be replaced by the End User. It's rare that they'd be sealed inside, but that does happen at times. The big issue is finding replacement batteries of same type/size fit, and you'd need to do that online.

Please discard. Probably a short circuit in the inverter!

It may not be dead yet. Does it supply output? You have not mentioned. It would be considered dead if it does not give any output. Is the battery fine? If the battery is fine and there is no output then it may be dead.
So, check the battery for any sign of life.
Check the output.
Check output with it plugged into mains.
If all are negative then it is dead.

just unplug the UPS and check for how long it runs on batteries, if time is short just replace the batteries. if you are using a line interactive UPS you may have to replace it by an online UPS
