A dry-cell battery is a device made of one or more
electrochemical cells that convert stored chemical energy into
electrical energy. It contains an electrolyte that is contained within a
paste or other moist medium.
A standard dry cell battery
includes a zinc anode and a carbon cathode within a central rod.
Cadmium, carbon, lead, nickel, and zinc are used to manufacture
different dry cell designs and capabilities, with some models more
suitable for certain devices than others.
In contrast to wet-cell batteries, dry batteries do not spill, which makes them ideal for portable equipment.
- Primary dry cell batteries (e.g., dry cell primary leclanche, alkaline primary, and lithium type batteries);
- Portable rechargeable batteries (e.g., sealed nickel cadmium, nickel metal hydride, lithium, and zinc air); and
electric lighting devices designed to be hand-carried or worn on the
person and utilizing a self-contained or attached power source (e.g.,
general purpose, industrial, penlight, novelty, and military types).
