Before one year when i was turning on the ups alarm was beep-ing for long time, not battery alarm but caution alarm. Now I tried to open it , battery is completely dead (0 Volt). Also ups doesnt give any singal all led/alarm/light are off even power button. So does it worth to buy new battery or UPS is dead? How to know what is wrong ? Battery cost half money of UPS

If the battery lasted for less than a year it is still under warranty and I would return it. I have three and replace the batteries about every three to four years. None are less than ten years old.

UPS is 5 year old
As i see on manual
Before one year : Red ON and beep keep alarm. Potential internal failure. Restart UPS. If red LED
still light, call for assistance.
Now : All dead
