It depends upon the type of UPS.

A true UPS requires a battery to be connected to the inverter at all times. Mains power is used to charge the battery constantly and battery is required to continually supply power to the inverter which then converts the voltage to mains supply voltage.

A lower powered and cheaper type UPS areswitch-over types, when the mains supply fails, the UPS switches over to thebatteries and the inverter in milli-seconds which then supplies mains power to thecomputer and peripherals.
This type UPS may operate without a battery, but it depends upon the design of the UPS and the battery error detection system In most cases I doubt it can operate without a battery. You can try the UPS without a battery, make sure the battery terminals do not short against each other.

Good day!

You have to do is:
Check the battery if it is leak.Use a voltmeter to test the output voltage of the battery.If your battery had a low supply voltage even you charge it for 3 hours and above.Replace the battery immediately.


Thank you and good luck.

Please dont vote me down as I'm speculating at a guess. Please repost your question if i cant help you.
Do you live in an area with ice, water or snow. Do you have a power cord connected to it laying anywhere near those. You may have a short on any device. Batteries do lose charge though i'm not sure how much "units" means as a value. Power transformers generally have diodes, so you may have a problem with that to ground.
So check for shorts. Unplug everything, turn off charge power and see how much is lost over a day to test your batteries.

Can i have all the basic details of UPS system


UPS come in two types, lower powered cheaper types are usually switch over power.
These units senses a power outage and then switch over to the battery power to generate mains supply. The switch over occurs in milli-secs and does not affect the computer.
True UPS types constantly run off battery power to generate mains supply so there is no switch over time lag. These units are higher powered and higher costs units.

Both type of UPS have the same components.
Battery charger.
Batteries
Inverter that converts battery voltage to mains voltage
Electronic controls

My ups is not working. it is not responding on main power supply neither backing up.


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. There maybe one battery in a set of batteries that is faulty and causes the whole battery system to fail and indicate a battery fault.

These lower powered and cheaper KVA type UPS are switch over types, when the mains supply fail, the UPS switches over to the battery and inverter in milli-seconds which then supplies mains power but the power waveform is a pseudo sine wave (ie not a true sinewave. A faulty inverter circuit and or flat batteries won’t deliver standby power when the mains supply fails.

When UPS is shut down the lights go out on front pannel but power remains on plugs. It is coming from the AC side not the battery.


The UPS has a fauly/problem.
If your UPS is approx. 600VA, then it is not a true UPS unit but a switch over type. When the mains power fails the UPS switches over to the battery and inverter in milli-secs to provide mains power.
If you turn off the mains supply and shut down your UPS, but you are still getting mains power, then there is a fault with the switch over circuit.
You need to get this unit serviced.
