THE LEAD CALCIUM BATTERY. PART I. INTRODUCTION AND BACKGROUND
Abstract
Essential characteristics of the Pb acid cell, and particulars of full float operation in terms of the individual plate potentials and the state of charge of the cells are described. When fully charged, the current is erratic and is determined by the negative plates. This small current is just sufficient to counteract selfdischarge. The positive plates in a floating cell are polarized very slightly above their open circuit voltage and do not vary with the fluctuating float current. Following discharge, the battery in float service is recharged automatically at the constant voltage selected for float. Certain restrictions are imposed upon the balance of negative and positive plate areas in the individual cells; all cells in a battery must be nearly equivalent to float simultaneously, and the cells must be capable of maintaining capacity when operating at maximum efficiency.
