Iyini ibhethri ebandayo yama-amps e-cranking?

Ama-Cold Cranking Amps (CCA)isilinganiso sekhono lebhethri lokuqala injini emazingeni okushisa abandayo. Ngokucacile, ikhombisa inani lamanje (elikalwa ngama-amps) ibhethri elishajwe ngokugcwele elingu-12-volt elingalethwa imizuzwana engama-300°F (-18°C)kuyilapho igcina i-voltage okungenani7.2 volts.

Kungani I-CCA Ibalulekile?

1. Ukuqala Amandla Esimo Sezulu Esibandayo:
   • Amazinga okushisa abandayo anciphisa ukusebenza kwamakhemikhali ebhethrini, ehlisa amandla ayo okuletha amandla.
   • Izinjini nazo zidinga amandla engeziwe ukuze ziqale emakhazeni ngenxa yokuqina kukawoyela nokukhuhlana.
   • Isilinganiso esiphezulu se-CCA siqinisekisa ukuthi ibhethri inganikeza amandla anele ukuqala injini kulezi zimo.
2. Ukuqhathaniswa kwebhethri:
   • I-CCA isilinganiso esimisiwe, esikuvumela ukuthi uqhathanise amabhethri ahlukene ngamakhono awo okuqalisa ngaphansi kwezimo ezibandayo.
3. Ukukhetha Ibhethri Elilungile:
   • Isilinganiso se-CCA kufanele sihambisane noma sidlule izimfuneko zemoto yakho noma okokusebenza, ikakhulukazi uma uhlala endaweni ebandayo.

Ihlolwa Kanjani I-CCA?

I-CCA inqunywa ngaphansi kwezimo eziqinile zaselabhorethri:

• Ibhethri lipholile ku-0°F (-18°C).
• Umthwalo ongashintshi usetshenziswa imizuzwana engu-30.
• Amandla kagesi kufanele ahlale ngaphezu kwama-volts angu-7.2 ngalesi sikhathi ukuze ahlangabezane nesilinganiso se-CCA.

Izinto Ezithinta I-CCA

1. Uhlobo Lwebhethri:
   • Amabhethri E-Lead-Acid: I-CCA ithonywa ngokuqondile ubukhulu bamapuleti kanye nendawo ephelele yezinto ezisebenzayo.
   • Amabhethri e-Lithium: Nakuba engalinganiselwe yi-CCA, ngokuvamile asebenza ngaphezu kwamabhethri e-lead-asidi ezimeni ezibandayo ngenxa yekhono lawo lokuletha amandla angashintshi emazingeni okushisa aphansi.
2. Izinga lokushisa:
   • Njengoba izinga lokushisa lehla, ukusabela kwamakhemikhali ebhethri kuhamba kancane, kunciphisa i-CCA yayo esebenzayo.
   • Amabhethri anezilinganiso eziphezulu ze-CCA asebenza kangcono ezindaweni ezibandayo.
3. Ubudala Nesimo:
   • Ngokuhamba kwesikhathi, amandla ebhethri kanye ne-CCA kuyehla ngenxa yokushibilika, ukuguga, kanye nokuwohloka kwezingxenye zangaphakathi.

Ulikhetha Kanjani Ibhethri Ngokusekelwe ku-CCA

1. Hlola Imanuwali Yomnikazi Wakho:
   • Bheka isilinganiso esinconyiwe se-CCA semoto yakho.
2. Cabangela Isimo Sezulu Sakho:
   • Uma uhlala endaweni enobusika obubanda kakhulu, khetha ibhethri elinesilinganiso esiphezulu se-CCA.
   • Ezimweni ezifudumele, ibhethri eline-CCA ephansi lingase lanele.
3. Uhlobo Lwemoto Nokusetshenziswa:
   • Izinjini zikadizili, amaloli, nemishini esindayo ngokuvamile idinga i-CCA ephakeme ngenxa yezinjini ezinkulu kanye nezidingo zokuqalisa eziphezulu.

Umehluko Obalulekile: I-CCA vs Ezinye Izilinganiso

• Umthamo Wokulondoloza (RC): Ibonisa ukuthi ibhethri lingaletha isikhathi esingakanani intambo engashintshi ngaphansi komthwalo othile (osetshenziselwa ukunika amandla ama-electronics lapho i-alternator ingasebenzi).
• Isilinganiso se-Amp-Hour (Ah): Imele isamba somthamo wokugcina amandla ebhethri ngokuhamba kwesikhathi.
• I-Marine Cranking Amps (MCA): Ifana ne-CCA kodwa ikalwa kokuthi 32°F (0°C), iyenze icaciselwe amabhethri olwandle.
