Ni-Cds: the memory lingers on.
The medical photographer's source of power for portable electronic flash has evolved from the disposable, single-use battery via the wet cell to the nickel-cadmium rechargeable battery, and recently to the 'dry-fit' rechargeable battery. This paper looks at the ubiquitous nickel-cadmium rechargeable battery with reference to its charge/discharge cycling and chemical 'memory' during discharge, and compares single-use and other rechargeable batteries with respect to ease of use, capacity and working life.
