What Does NiCad Mean and How Is It Related to Cameras and Photography?

When talking about cameras and photography equipment NiCad is the name given to a common type of rechargeable battery. NiCad batteries were one of the first successful standards of rechargeable batteries used in digital cameras. NiCad stands for ‘nickel-cadium’ and relates to the materials used within the battery to provide an electrical output. Nikel-cadium batteries have now widely been superseded by NiMH batteries which typically hold two or three times the charge capacity of their NiCad counterparts. NiCad batteries are however still available for equipment originally designed to run on them.
