Hi All, Just returned from a flight and recharging the batteries, one of them when I press the red button, no LEDs light up, this registered as an anomaly, but I plugged it in the charger and it started charging from the 2nd LED up... LED 1 was not lighting up?! Had a quick chat with DJI and he asked for a screenshot of the battery screen, all was normal (see attached) and he advised I pop it in the Inspire, switch it on to idle and drain the battery until it just switches off. Did that and came back everything was dead - ok, plugged it back in the charger and same thing was happening... Left it again and came back when the battery LEDs were all off and when I press the battery button, only the top 3 LED's light up... (See pics) What does this mean? a dead cell? (incidentally, how many cells in the inspire 1 battery)? Battery screen still showing all ok... had another chat with DJI and this time, he says Battery has expired - was sorry and said I need to buy a new one... So is it true? a battery with 18 charges and 96% battery life is now dead and unsafe to use? Battery is about 8 months old, but obviously not heavily used.
