NICKEL CADMIUM CELLS FOR USE IN PORTABLE INSTRUMENTS AND SEVERAL METHODS OF RECHARGING THEM

Abstract

An evaluation is presented of several types of nickel cadmium rechargeable cells under consideration for sealed and nonsealed portable instrument systems. Temperature, discharge rate, capacity, rechargeability and interchangeability were found generally satisfactory where the different terminal voltage requirements per cell were compatible with the existing instrument. Types of cells ranging from the D size down to a button type of 50 ma-hr capacity were tested and methods of recharging them considered. A universal, series regulator type charger is discussed which will charge these cells in the constant voltage mode. Also discussed is a silicon solar cell charger for use where adequate light is available. (Author)
