Some discharge characteristics of lead acid batteries

This paper discusses the fundamental processes involved in the production of current in a lead acid cell, particularly as they are related to the peformance of the cell when furnishing variable or intermittent loads or a combination of both. A method of determining the size of cell required for various duty cycles is described and a general equation is derived, which, with certain restrictions, will indicate the number of positive plates required in each cell of a battery of the type selected for the application.
