After battery is discharge because power failure, ups is not automatically working even there is power supply

Check on the back of the UPS to see if the input circuit breaker has tripped. Are you getting any lights on the front LED's? Also disconnect all loads and ensure nothing is plugged into the output receptacles. Also open UPS up and ensure the input fuse is not blown. You will need a meter to check this out.

Batteries in the UPS typically last 3 to 5 years and it depends upon several factors. Including the number of times the unit must go on battery power and environmental conditions. There are usually several batteries in the UPS and while the battery voltage may show 13 volts, this may only be a float charge/voltage and a true indication of the battery voltage and condition requires the batteries to be tested under a load. If one battery is faulty in a set of batteries it will causes the whole battery system to fail and indicate a battery fault.
A faulty charging circuit will not charge the batteries and will also cause a fault condition.

My Liebert PSA itON 600 UPS keeps beeping when i turned it on

To figure out what's wrong with the UPS, first you have to do a few things.

When calculating the rating a UPS can handle, it's voltage x amperage. If it's Watts multiply the number by 1.67 to give the rating of the device.

Add up all the devices (use the power supply rating in the computer) as well as any other device, and add them up.

If this rating was exceeded, then you have overloaded the UPS. If it was too long that you did this, then you wore out the battery.

When a UPS beeps even when not connected, that means the battery is very weak.

If the battery is more than 3 years old, it will need to be changed. If the online tests of the unit were done and the battery doesn't need replacing, then other parts of the UPS need fixing.

Check the battery.
