I have one Mavic Battery that is fully charged (4 green Lights , but won't turn on ).  battery in the drone, one short push on Power button 4 green lights, one long push , 4 green lights but then they turn off. no power to drone . also its been a month and battery is not discharging. I tried to discharge the battery manually with the supplied coupling to charge phone , power wont turn on.  I cant go on DJI asist to try updating because the battery wont turn on. Has anyone had this issue and found a soloution ? As near as i can tell, with out entering the battery software ive made 30 flights on that battery . I have 3 Batteries that i rotate so, only 90 flights all togetherdevided equally between the 3 batteries .
Thanks Sean
