Pureit Advanced Water Purifier — Premature expiry of the battery

Address:

Aligarh, Uttar Pradesh

Sir,
I am a retired person and live in aligarh with my wife. I have been using advance model of pureit since this february. Ever since i have replaced my batteries twice and to my shock, is ready for the same again. I got replaced my second battery of 1500 liters on 4 july 2015 and today (16 september 2015) my battery’s indicator is wholly red. Under no circumstances can my wife and myself, consume 1500 liters of water in less than two and a half months. If this trend continues i will be spending at least 4000 rs, in replacing kits of my purifier. I demand an explanation from the authorities whether i have made a istake by choosing pureit as my purifier.
