It looks like empty battery,like dead empty....hook up charger to battery,wait 30 seconds,unplug it then plug iit back on,do that 10 times,see if that will help...some people had luck by tricking charge,what they did was hook up good battery to charger then switch to empty battery really fast and so few times till charger stops flashing....if you get lucky and it works dont fly with that battery yet,like mike said something could be wrong with battery,hook it up to bebop and let it hover few feet above ground till battery charge gets low,look for fast sudden drops in charge,if you see anything like that its it probably bad cell in battery,send it back
