Dry Battery


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.

Products include:

  • 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
  • Portable 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).

NEMA Members develop and influence Standards, codes, regulations, and legislation on primary dry battery products.

Activities

  • Works with other Standards development and certification organizations (e.g., Underwriters Laboratories) on issues related to harmonization, testing, certification, and establishing effective dates for new requirements
  • Participates on committees with the International Electrotechnical Commission (IEC) U.S. National Committee and the American National Standards Institute, Inc. (ANSI) to unify industry positions on legislative and regulatory matters related to harmonization of dry battery products
  • Collaborates with other associations and advocacy groups and other industry associations in Australia, the European Union, Japan, and Latin America to support efforts related to battery technologies, recycling, and transportation
  • Supports the management of a battery ingestion telephone hotline and website to aid in positive medical treatment outcomes and to educate consumers on the hazards associated with accidental battery ingestion
  • Manages NEMA Members' government relations in the United States and Canada related to responsible battery-recycling legislation and associated collection and recycling programs
