Hi, I accidentally put battery in reverse position in this charger and result was some amount of smoke.
After inspecting the board I found a damage transistor. It was shorted and after removing some of the functions of the charger started working again. This element is part of charging circuit and now it is not charging any batteries.
My question is how to determine exact specs of this transistor? It is in body SOP-23-3 and writing on it is "ALSF 12"and 12 is rotated on 90 degrees.
I'm adding also picture of this part of the board.
Thanks
