The Ag/Cd cell has an vitality density close to that of the Ag/Zn system but with the benefit that it is nonmagnetic. This cell has a 95% effectivity of cost acceptance, however battery efficiency declines beneath 0°C and above 40°C. This cell is used in appliances, power tools, and satellites, the place nonmagnetic properties are important, and to energy submarine simulator target drones. The Ag/Fe cell has the advantage of a excessive discharge price capability with the cycling characteristics of the iron electrode.
