Around 3 yaers ago I am purchase microtek ups of 1 kg with dual batterys of microtek and fit this system in my home after 1 month use this ups I am very happy beacuse battery bakup is very good of this and this is save energy .when I am buy this product then I am spent around rs 8 thousand on ups and 14 thousands on each battery but now my ups complete our 3 year but I m not spent any single money on it . My home energy consumption is around 4 fans 2 led tv and 4 to 5 lights but my ups never disappointed me and this is give me around 8 to 10 hour bakup I think this timing of bakup is good for any ups so I like microtek ups and batterys
