I am using this ups from 2012 and guys trust me this ups is really worthy I was purchased this ups in 2012 in RS 2400 from local market after unbox my ups I was charged it for 10 to 12 hours as written in instruction on the box. this ups gives me an average backup of about 35 to 40 minutes. In 4 years only battery is replaced worth rs 600 from microtek official shop.
This ups is best for home purpose if your usage is basic on your pc and you need 30 minuted backup then go for it without any second thought this is single battery. Long life ups total value for money
