Sealed Ni–Cd cells may be used individually, or assembled into battery packs containing two or more cells.
Small cells are used for portable electronics and toys (such as solar garden lights), often using cells manufactured in the same sizes as primary cells.
When Ni–Cd batteries are substituted for primary cells, the lower terminal voltage and smaller ampere-hour capacity may reduce performance as compared to primary cells.
Miniature button cells are sometimes used in photographic equipment, hand-held lamps (flashlight or torch), computer-memory standby, toys, and novelties.

Specialty Ni–Cd batteries are used in cordless and wireless telephones, emergency lighting, and other applications.
With a relatively low internal resistance, they can supply high surge currents.
This makes them a favourable choice for remote-controlled electric model airplanes, boats, and cars, as well as cordless power tools and camera flash units.

Larger flooded cells are used for aircraft starting batteries, electric vehicles, and standby power.
