My ups beep continuosly and then shuts off. - Computers & Internet

Classic signs of a worn out battery. Battery International has a great cross reference to find your battery: http://www.batteryinternational.com/ups-batteries.html

This normally happens when the reserve battery in the UPS has run out of power. It can be caused by the battery not being charged by the UPS circuitry or by the fact that the battery is old and will no longer hold sufficient charge to make the UPS work correctly in the event of a mains power failure. Some UPS systems have computer connection so that the status of the UPS can be monitored and configured.

Check that your ups mains cord is connected to AC Power Supply. This happens due to low voltage / no supply ion AC outlet.

It needs to be charged or pluged in. If that has already been done, it's not charging and the internal or external fuse is blown.

Ur battery life is gone.....replace it.....
