NickleCadmium cells are the most common type of rechargable battery. They have a highenergy density and a EMF of V. They can be recharged more times than other types of rechargable batteries but unless they are fully discharged before recharging suffer from a memory effect which reduces their capacity to store charge.

Their high strength, up to 68,000 psi yield and 120,000 tensile, permits them to be used at unit loads up to 50 percent higher than those for leaded tin bronze Alloy C93200. Because of their high strength, however, they have fairly low ductility and do not conform or embed well. They consequently require shafts hardened to 550600 BHN.
