What Is a NiCd Battery?
A NiCd battery is a battery which uses nickel and cadmium as its electrodes. It is generally pronounced nigh-cad, although many people also simply say nickel cadmium. It is important to note that although Ni and Cd are chemical symbols for the pure elements, a NiCd battery actually uses nickel oxide hydroxide and metallic cadmium in its operation. The NiCd battery is one of the most commonly-used types of rechargeable battery, and is seen widely in consumer applications. Most primary cells used in batteries have a nominal potential of 1.5V, which is higher than that of a NiCd battery, which is 1.2V. However, most primary cells also have a variable voltage, which reduces as the battery expends its charge. In most batteries this can get as low as 0.9V, whereas a NiCd battery loses very little cell potential as it runs down, so that even as it approaches a complete loss of charge it is still generating around 1.2V. As a result, most devices intended to run on batteries can use NiCd batter
