AD-X2 was an additive purported to extend lead–acid automotive battery life, marketed by California bulldozer operator Jess M. Ritchie in the late 1940s and early 1950s. After it was declared ineffective by the National Bureau of Standards (NBS), and other government agencies accused Ritchie of fraud, a media blitz alleging collusion between battery manufacturers and the government led Commerce Secretary Sinclair Weeks to request NBS director Allen V. Astin’s resignation.
