Comumente utilizadas em aplica\u00e7\u00f5es de m\u00e9dia drenagem, como brinquedos, lanternas e instrumentos musicais, as baterias C possuem capacidade significativamente maior que as baterias AA. Diversas qu\u00edmicas s\u00e3o empregadas em sua constru\u00e7\u00e3o, influenciando a tens\u00e3o terminal, capacidade e taxas pr\u00e1ticas de descarga, embora dispositivos projetados para c\u00e9lulas C geralmente suportem apenas de 1,2 a 1,5 V, a menos que especificado pelo fabricante.<\/p>\n<h2>Tipos de Bateria C<\/h2>\n<p>As baterias C s\u00e3o divididas em prim\u00e1rias e secund\u00e1rias:<\/p>\n<ul>\n<li><strong>Bateria Prim\u00e1ria:<\/strong> Inclui as baterias alcalinas, de l\u00edtio met\u00e1lico, zinco-carbono e zinco-cloro.<\/li>\n<li><strong>Bateria Secund\u00e1ria:<\/strong> Abrange as baterias NiMH e NiCd, que s\u00e3o recarreg\u00e1veis.<\/li>\n<\/ul>\n<h2>Funcionamento e Composi\u00e7\u00e3o<\/h2>\n<p>Uma bateria el\u00e9trica \u00e9 uma fonte de energia el\u00e9trica DC, convertendo energia qu\u00edmica armazenada em energia el\u00e9trica por meio de um processo eletroqu\u00edmico.
