Ni-Cd Batteries

The nickel-cadmium or NiCd battery is a rechargeable battery that uses a nickel oxide hydroxide and metallic cadmium as electrodes. NiCd batteries are fast to charge and can take a high number of charges if properly taken care of and not misused. Ni-Cd cells are available in the same sizes as alkaline batteries, from AAA through D, as well as several multi-cell sizes, including the equivalent of a 9 volt battery. They can be used in RC airplanes, boats, and cars, as well as cordless power tools, photographic equipment, flashlights, and toys.
