I purchased a intex UPS worth Rs. 1700, 7 years ago for my desktop pc. One year warranty. It gives 15 minutes backup power after electricity goes. Its well control electricity fluctuation. It contain a dry battery which expires after approx. 3 years. Then you have to install a new dry battery for it from pc shop or any battery shop. Intex service in our region is very fast . If you have any problem in your UPS in warranty then just visit your nearest intex service center. Actually a UPS is a power stablizer+ power backup battery.
