Zebronic ups is a wrost ups. Our organisation have taken 5 new zebronic ups due to low price as compare to other branded ups. But it was wrong decission by our organisation. After 4 to 6 month all ups are damaged. The ups are unable to take load maximum 3 to 5 min. The battery use by zebronic ups is very poor quality. But there is no circut problem. After replacement of batteries, the ups are running.
