Image title	The battery-testing controversy which began in 1948 was caused by the testing of a material - a'battery additive'- marketed under the name'Battery AD-X2'. This product, when added to a lead-acid battery, allegedly improved its performance and, under some circumstances, could presumably revive a'dead'battery. This incident caused congressional hearings, newspaper headlines, and charges of Bureau bias against the'little guy.'California Senator William F. Knowland requested that the National Bureau of Standards test AD-X2 on behalf of a constituent.
