I bought this apc bx600cl-In ups with my personal computer, at a price of 3000rs as I used it for 1year that is why I am sharing my experience with you people.First of all, the I want to say that the battery back up of this ups is very poor.When I just bought this ups it gave around 10mins of backup but as the time passed the backup got decreased to 3minutes hardly.I took it to the repair shop and they told me that the battery is not working properly, so you have to change it.So I paid for replacement of new battery which is 800rs.I thought that now it will work properly but after a couple of months same problem started persisting again.So finally I dumped this UPS and bought a new one of luminous which is working fine now.So people I do not recommend this ups to anyone, think before buying!
