ʻO nā ʻōhua alkaline kahi ʻano o ka pilahi hoʻohana e hoʻohana ana i ka electrolyte alkaline, maʻamau ka potassium hydroxide, e mana i nā mea uila liʻiliʻi e like me nā mana mamao, nā mea pāʻani, a me nā kukui uila.Uaʻikeʻia lākou no ko lākou ola lōʻihi a me ka hana hilinaʻi, e hoʻolilo iā lākou i koho kaulana no ka nui o nā mea uila uila.Ke hoʻohana ʻia ka pākaukau, loaʻa kahi hopena kemika ma waena o ka anode zinc a me ka cathode manganese dioxide, e hana ana i ka ikehu uila.

Hoʻohana maʻamau ʻia nā pākahi alkaline i nā ʻano mea hana o kēlā me kēia lā, e like me nā mana mamao, nā kukui uila, nā mea pāʻani, a me nā mea uila uila.Uaʻikeʻia lākou no ka hāʻawiʻana i ka mana hilinaʻi a he lōʻihi ka lōʻihi o ka mālamaʻana, e kūpono ana iā lākou no nāʻano likeʻole.Eia nō naʻe, he mea nui e hoʻomaopopo i ka hoʻolei ʻia ʻana o nā pākahi alkaline i mea e hōʻemi ai i ko lākou hopena kaiapuni no ka mea, aia nō kekahi mau ʻona alkaline i nā mea pōʻino, e like me ka mercury, nā metala kaumaha e like me ka cadmium a me ke alakaʻi.Inā ʻaʻole e hoʻolei pono ʻia kēia mau pila, hiki i kēia mau mea ke lele i loko o ka lepo a me ka wai, e hoʻopilikia ai i ke kaiaola.He mea nui ka hana hou ʻana i nā pākahi alkaline e pale i ka hoʻokuʻu ʻia ʻana o kēia mau mea ʻino i loko o ke kaiapuni.

ʻO ia ke kumu e hiki ai i ka hoʻohana ʻana i nā pākahi alkaline me ka mercury ʻole ke kōkua i ka pale ʻana i ke kaiapuni.He mea ʻawaʻawa ka Mercury i hiki ke loaʻa nā hopena pōʻino i ke kaiapuni a me ke olakino kanaka.Ma ke koho ʻana i nā pākaukau me ka 0% mercury, hiki iā ʻoe ke kōkua i ka hōʻemi ʻana i ka hopena maikaʻi ʻole o nā mea pōʻino i ke kaiapuni.Eia hou, he mea nui ia e hoopau pono a hana hou i na pila no ka hoemi ana i ka hopena o ke kaiapuni.Ke koho neinā pāʻani alkaline me ka mercury ʻolehe hana maikaʻi i ka mālama ʻana i ke kaiapuni.
ʻOiai he mea maikaʻi ke hoʻohana hou ʻana i nā pākahi alkaline, he mea koʻikoʻi nō hoʻi ka ʻimi ʻana i nā koho ʻē aʻe, ʻoi aku ka maikaʻi o ke kaiapuni, e like me ka hoʻohana ʻana i nā pākaukau rechargeable (Eg:AA/AAA NiMH Hiki ke hoʻouka hou ʻia,18650 lithium-ion rechargeable pākaukau) a i ʻole e ʻimi ana i nā huahana me nā kumu ikehu mau loa (Eg:kaha kiʻekiʻe AAA Alkaline pākahiko,kaha kiʻekiʻe AA Alkaline pākahiko).ʻO ka mea hope loa, hiki i ka hui pū ʻana o ka hoʻokuʻu kuleana a me ka neʻe ʻana i nā mea ʻokoʻa hoʻomau hiki ke kōkua i ka mālama ʻana i ke kaiapuni.
