Mine was the 11th batch as well. I plugged mine into my galaxy s4 wall charger and cable with the dx50 powered off and it immediately had the green circle that said charged. Not sure why it has the period but it does.
Does it have the same green circle when it is charging if so does it say charged. when it is charging as well?
Really? It's not that bad and english is not the primary language for alot of people here...
I just ordered the super deluxe nirvana in utero 20th anniversary and a 64gb micro sd card in preparation for the dx50.
