Ups is dead, no singals
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
Is this a good question?
