Question: are black and decker and dewalt 20v batteries the same?
Answer: One, a whole bunch of the top power tool brands — including DeWalt, Black & Decker, Craftsman, Porter-Cable and more — are all owned by the same company, Stanley Black & Decker. Those 20-volt lithium-ion battery cartridges you stick into your drill, circular saw and weed whacker are all pretty much the same thing.
