Took 2 batterys out of the case today, put on the table (to charge them) and sudenly after two seconds they both turn themselfs on. I didnt belive my eyes, started to think that maybe i touched button by mistake (but not two battery together). And also i didnt connect the charger. I had 3 more batterys in the case, immediately i trieid the same with those also, third battery make the same thing (gently took out of the case, put on the table, and it turned itself on after 2-3 seconds). Fourth and fift battery didnt do that, tried many times. The batterys that turned itself on, after i powerd them off, and trieid the same move again, also stays off. Little bit confusing!!! I think its not normal? All five batterys was flown one day earlier down to 25-30% and stored to DJI stock case. Maybe i am missing something, but i think its not normal, that they turn on by themself, its kind of dangerous. All five batterys are updated to latest firmware and flown mane times after update.
