Though i have never used Millat battery but after some research on net i came to conclusion that have a battery somewhat near to deep cycle..i have used osaka/volta ups specialized deep cycle battery and it was a crap and behaved like automobile battery died in 10 months coz of a dead cell and other automobile batteries of osaka/volta they also died within a year coz of a dead cell, AGS i used died with in one year and same is the case with exide and phoenix batteries non of them was able to enter 2nd season of summer though one thing i noticed about exide there intial backup time is good compared to others...ok so why i suggest millat to you . following are the reasons
1.https://www.pakwheels.com/forums/non-wheels-discussions/191767-best-battery-ups read post number 19 here and look closely at UPS battery pic of millat and count the number of plates attached to both terminals ..with one terminal there are 9 and with other 8 so total 17 plates...whereas automobile battery within the same dimension battery have 21 or 23 plates...so it means plates are thicker with pocket type insulator to prevent accumulation of fallen lead debris in the bottom thus preventing shorting of cell...one major cause of our battery failure due to deep discharges(which we cant control due to long and frequent hours of load shedding) and overcharging( we can take care of it as briefly discussed by Our Dear Brother Talha Waheed).
