Description

Dry cell battery made by Harvey & Peak, Charing Cros Road, London. The demand for portable cells led to the introduction of dry cells. These are generally modifications of the Leclanche cell in which damp pastes are used instead of liquids, and each cell is sealed at the top. Pioneering chemist Carl Gasner patented his first dry cell in the USA on 15 November 1887 (Patent No 373064); this type, introduced a year later, was the first dry cell to attain any succes.
