I have an 18 volt Firestorm based tool which uses 18 volt Dewalt batteries. I was wondering since Black and Decker makes Dewalt tools, is there any interchangeability between their batteries and tools. I was thinking of using Black and Decker batteries for my 18 volt Firestorm based tools. Can I do it? How can I use those batteries in my tools? Is there any possibility of any disaster in doing so? I would really appreciate your feedback pertaining to this. Thanks.
