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

Your not asking the right question. The answer is dependent upon how long you want the backup to work. Does a battery fit in the unit or is it alone? If you were to connect a car battery to the unit it would run for many hours, say a motorcycle battery would run maybe an hour. It is all about the time you want for run time.
