You are very right and now I am again back to square one which UPS to choose there are lots of options and no way to know which UPS provide 3 step charging there is not enough technical data at their sites My current homeage UPS has two step charging, And I have no way to equalize charge if required, therefore I have also plans to buy custom made desi charger with variable current and voltage the guy at hallroad gave me a quote of Rs.5000 for such charger 10amp
I do have shortlisted CyberPower and Deutsche Power, I just don't like desi ups because of dozens more quality variables ...
I sold my batteries in May2017 for Rs.2500 only
I am in Lahore and purchased batteries from Phoenix dealer at wahdat road
At the end of the day there are so many odds for this setup to work smoothly , first you should be lucky to have a genuine battery then you should pray it doesn't have any manufacturing fault then you need a good UPS again no way to know if it is a fresh piece or a repaired one, also a brand may have worked good for someone in the past but what if they suddenly dropped their quality or fucntions ....??? Life in pk just sucks .... or maybe I am the most unlucky one
