The Short Version: A Dewalt DC9310 1-Hour Charger is a good replacement for a Black and Decker Firestorm battery charger. It costs significantly more than the original but based on reviews it is far more reliable and safer. It won’t overcharge the batteries. In addition, it will work with many current Dewalt batteries (according to my older brother it’s the same charger he uses with his Dewalt NANO batteries).
