I te mea kei te piki haere te maha o ngā taputapu hiko e whakamahia ana i runga i te waka tere moana hou, ka tae mai te wā e hiahia ana kia whānuitia te pēke pākahiko kia tutuki ai ngā hiahia e piki haere ana mō te hiko.
He mea noa tonu te whakamahi i tētahi pākahiko tīmatanga miihini iti mō ngā poti hou, me tētahi pākahiko ratonga iti rawa te kaha – arā, te momo mea ka taea te whakahaere i tētahi pouaka whakamātao iti mō ngā hāora 24 anake i mua i te hiahia ki te whakakī anō. Tāpirihia ki tēnei ko te whakamahinga o tētahi mata hiko, rama, taputapu whakatere me tētahi pailota aunoa, ā, me whakahaere e koe te miihini i ia ono hāora pea.
Mā te whakanui ake i te kaha o tō pēke pākahiko ka taea e koe te whakawhiti i waenga i ngā utunga, te keri hōhonu rānei i ō rahui mēnā e tika ana, engari he nui atu ngā mea hei whakaaroaro i tua atu i te utu o tētahi pākahiko tāpiri: he mea nui kia whakaarohia te tikanga utu me te hiahia kia whakapai ake i tō rihi hiko takutai, i tō alternator, i tō whakaputa hiko rerekē rānei.

E hia te mana e hiahiatia ana e koe?

I mua i tō whakaaro ka nui ake te hiko e hiahiatia ana e koe ina tāpirihia he taputapu hiko, he aha e kore ai e arotakehia ō hiahia. He maha ngā wā ka kitea he penapena hiko pea mā te arotake hohonu i ngā whakaritenga hiko kei runga i te waka, ā, ka kore pea e hiahiatia he tāpiri i te kaha tāpiri me te pikinga o te kaha utu.

Te mārama ki te kaha
Ka taea e te aroturuki te āwhina i a koe ki te pupuri i ngā taumata pākahiko hauora kia roa ake ai te ora o te pākahiko
He wā tika hei whakaaro ki te tāpiri i tētahi atu pākahiko ko te wā e tata ana koe ki te whakakapi i te mea o nāianei. Pērā ka tīmata anō koe me ngā pākahiko hou katoa, he mea tino pai tonu tēnei – ki te kore, ka taea e te pākahiko tawhito te tō i tētahi pākahiko hou ina tae ki te mutunga o tōna oranga.

Waihoki, ina tāutahia he peeke ā-rohe e rua ngā pākahiko (neke atu rānei), he mea tika kia hoko pākahiko o te kaha ōrite. Ko te whakatauranga Ah e tino tohuhia ana i runga i ngā pākahiko waatea, i ngā pākahiko huringa-hohonu rānei, e kiia ana ko tōna whakatauranga C20, ā, e pā ana ki tōna kaha ariā ina tukuna i roto i te wā 20-hāora.
He angiangi ake ngā pereti o ngā pākahiko tīmatanga miihini hei aro atu ki ngā ngaru tere poto, ā, he maha ake te whakatauranga mā te whakamahi i ō rātou kaha Cold Cranking Amps (CCA). Kāore ēnei e pai mō te whakamahi i roto i te peeke ratonga nā te mea ka tere mate mēnā ka tukuna hohonu te hiko.
Ko ngā pākahiko pai rawa atu mō te whakamahinga ā-whare ka tapaina ko te 'huringa-hohonu', arā, he pereti matotoru ō rātou kua hangaia hei tuku i tō rātou kaha mā te āta haere, me te auau.

Te tāpiri i tētahi pākahiko tāpiri 'i te wā kotahi'
I roto i te pūnaha 12V, ko te tāpiri i tētahi pākahiko tāpiri he mea noa iho mā te whakairi tata rawa atu ki ngā pākahiko o nāianei, kātahi ka honoa whakarara, mā te hono i ngā pito 'rite' (pai ki te pai, kino ki te kino) mā te whakamahi i te taura whānui nui (70mm² te whānui) me ngā pito pākahiko kua whakapiko tika.
Ki te kore āu taputapu me ētahi taura taumaha e iri ana, ka tūtohu atu ahau kia ine koe i te rahi o ngā mea e tika ana, kia hangaia hoki ngā hononga whakawhiti e te tohunga. Ka taea e koe te hoko i tētahi mīhini kume (ko ngā mea waipēhi te mea pai rawa atu) me ngā pūrua hei mahi māu ake, engari he nui rawa te haumi mō tētahi mahi iti pēnei.
I te wā e hono ana i ngā pākahiko e rua i te taha whakarara, he mea nui kia mōhio ko te ngaohiko putanga o te peeke ka noho tonu, engari ka piki ake tō kaha e wātea ana (Ah). He maha ngā wā ka pōhēhētia ngā amp me ngā amp hāora. Ki te kī māmā, ko te amp he ine i te rere o te iahiko, engari ko te amp hāora he ine i te rere o te iahiko i ia hāora. Nō reira, i roto i te ariā, ka taea e te pākahiko 100Ah (C20) te whakarato i te iahiko 20A mō ngā hāora e rima i mua i te korenga e mahi. Kāore e taea, mō ētahi take uaua, engari mō te māmā ka waiho e au kia tū.

Te hono i ngā pākahiko hou 'i roto i te raupapa'
Ki te honoa ngā pākahiko 12V e rua i roto i te raupapa (mai i te pai ki te kino, me te tango i te putanga mai i te tuarua o ngā pito +ve me te -ve), ka puta he putanga 24V, engari kāore he kaha tāpiri. E rua ngā pākahiko 12V/100Ah e honoa ana i roto i te raupapa ka whakarato tonu i te kaha 100Ah, engari i te 24V. Ka whakamahia e ētahi poti he pūnaha 24V mō ngā taputapu taumaha pēnei i ngā matapihi, ngā wini, ngā mīhini wai me ngā papu kaukau nui, nā te mea mā te whakarea i te ngaohiko ka haurua te kukume iahiko mō te taputapu mana kotahi.
Te parenga me te fiusi au teitei
Me tiaki tonu ngā pēke pākahiko ki ngā fiusi au-rahi (tata ki te 200A) i ngā pito putanga pai me te kino, ā, me tata tonu ki ngā pito, kaua e tangohia te hiko tae noa ki muri i te fiusi. Kei te wātea ngā poraka fiusi motuhake mō tēnei kaupapa, kua hangaia kia kore ai he mea e taea te hono tika ki te pākahiko me te kore e haere mā roto i te fiusi. Mā tēnei ka tino tiakina mai i ngā ara iahiko poto o te pākahiko, ka puta ai he ahi, he pahū rānei mēnā ka waiho kia kore e tiakina.

He aha ngā momo pākahiko rerekē?
He wheako me ngā ariā anō tō te katoa mō te momo pākahiko pai rawa atu mō te whakamahi i roto i temoanataiao. I ngā wā o mua, he nui, he taumaha ngā pākahiko waikawa mata (FLA) kua waipuketia, ā, he tokomaha tonu e whakapono ana ki tēnei hangarau māmā. Ko ngā painga ka taea te whakakī ki te wai māori me te whakamātautau i te kaha o ia pūtau mā te whakamahi i te hydrometer. Nā te taumaha o te taumaha, he tokomaha i hanga i tā rātou pēke ratonga mai i ngā pākahiko 6V, he māmā ake te whakahaere. Ko te tikanga hoki he iti ake te ngaronga mēnā ka pakaru tetahi pūtau.
Ko te wāhanga e whai ake nei ko ngā pākahiko waikawa-mata hiri (SLA), he mea e pai ake ana ki te tini mō ō rātou āhuatanga 'kāore he tiaki' me te kore e maringi, ahakoa kāore e taea te utu kaha pērā i te pākahiko pūtau-tuwhera nā te mea ka taea e rātou te tuku noa i te pēhanga hau nui i roto i te āhuatanga ohorere.
I ngā tekau tau kua pahure ake nei, i whakarewaina ngā pākahiko irahiko, he irahiko totoka te irahiko, kaua ki te wai. Ahakoa he hiri, kāore he tiaki, ā, he maha ake ngā huringa utu/tuku, me iti ake te kaha o te utu, me iti ake te ngaohiko i ngā SLA.
Nō nā tata nei, kua tino rongonui ngā pākahiko Absorbed Glass Mat (AGM) mō ngā poti. He mama ake i ngā LA noa, ā, kua mimitihia ō rātou electrolyte ki roto i te whāriki kaua ki te wai kore utu, kāore e hiahiatia he tiaki, ā, ka taea te whakairi ki tētahi koki. Ka taea hoki e rātou te tango i te iahiko utu nui ake, nō reira he iti ake te wā e hiahiatia ana hei utu anō, ā, ka ora i ngā huringa utu/tukunga maha atu i ngā pūtau waipuke. Hei whakamutunga, he iti ake te tere tukunga-ake o ēnei pākahiko, nō reira ka taea te waiho me te kore utu mō tētahi wā roa.
Ko ngā whanaketanga hou ko ngā pākahiko lithium. Ko ētahi e oati ana ki a rātou i roto i ō rātou āhua rerekē (ko te Li-ion, ko te LiFePO4 rānei te mea tino noa), engari me tino tupato te whakahaere me te tiaki i a rātou. Ae, he mama ake i tētahi atu pākahiko moana, ā, e kīia ana he tino pai ngā tatauranga mahi, engari he tino utu nui, ā, me whai pūnaha whakahaere pākahiko hangarau teitei hei pupuri i a rātou kia utua, ā, he mea nui ake, kia taurite i waenga i ngā pūtau.
Ko tētahi mea tino nui hei mōhio māu i te wā e hanga ana i tētahi peeke ratonga honohono, me rite te momo o ngā pākahiko katoa. Kāore e taea te whakaranu i te SLA, te Gel me te AGM, ā, kāore rawa e taea te hono i tētahi o ēnei ki tētahi atu.pākahiko e hangai ana ki te lithium.
