put my new battery on the charger tonight to charge charged it up and put the one that came with the phantom which was used but was told not used much on the charger and didn't have time to let it get fully charged so unplugged it and left it at home while I took the charged one out to fly came home and thought I would finish charging the battery plugged it in and nothing the light on the charger stays green and the lights on the battery don't even light up I know it's not the charger cause it works on the other battery if I take the battery off the charger and push the button on the battery it lights up and works in the phantom but won't charge at all what can I do with this
