Are Black+Decker, Porter-Cable, Stanley and Craftsman V20 20V batteries interchangeable?

Updated: June 15, 2026 | Garage Almanac

The Short Answer

Partly. Black+Decker 20V MAX, Porter-Cable 20V MAX and Stanley FatMax share one battery interface and DO interchange. Craftsman V20 and DeWalt 20V MAX are separate feet and do NOT, despite all being Stanley Black+Decker brands.

Same parent company does not mean same battery. The B+D / Porter-Cable / Stanley ‘value’ 20V packs are physically interchangeable with each other. Craftsman V20 uses a different foot, and DeWalt 20V MAX another. Third-party adapters exist to bridge these, but there is no native cross-fit between the value lines and DeWalt.
