Zithini ii-amps ze-cranking ezibandayo zebhetri?

Ii-Amps zeCold Cranking (CCA)yindlela yokulinganisa amandla ebhetri okuqalisa injini kumaqondo obushushu abandayo. Ngokukodwa, ibonisa ubungakanani bombane (olinganiswa ngee-amps) ibhetri ye-12-volt etshajiweyo ngokupheleleyo enokuyikhupha imizuzwana engama-30 kwi0°F (-18°C)ngelixa kugcinwa i-voltage ubuncinaneIi-volts eziyi-7.2.

Kutheni i-CCA ibalulekile?

1. Amandla Okuqalisa Kwimozulu Ebandayo:
   • Amaqondo obushushu abandayo ayacothisa iimpembelelo zeekhemikhali kwibhetri, nto leyo enciphisa amandla ayo okuhambisa amandla.
   • Iinjini zikwafuna amandla angakumbi ukuze ziqale xa kubanda ngenxa yeoyile etyebileyo kunye nokuxinana okwandileyo.
   • Umgangatho ophezulu we-CCA uqinisekisa ukuba ibhetri inokubonelela ngamandla aneleyo okuqalisa injini phantsi kwezi meko.
2. Uthelekiso lweBhetri:
   • I-CCA yireyithingi emiselweyo, ekuvumela ukuba uthelekise iibhetri ezahlukeneyo ngokwezakhono zazo zokuqala phantsi kweemeko ezibandayo.
3. Ukukhetha ibhetri echanekileyo:
   • Uvavanyo lwe-CCA lufanele luhambelane okanye ludlule iimfuno zesithuthi sakho okanye izixhobo zakho, ingakumbi ukuba uhlala kwindawo ebandayo.

Ivavanywa njani i-CCA?

I-CCA imiselwa phantsi kweemeko zelebhu ezingqongqo:

• Ibhetri ibanda ukuya kwi-0°F (-18°C).
• Umthwalo oqhubekayo ufakwa imizuzwana engama-30.
• I-voltage kufuneka ihlale ingaphezulu kwe-7.2 volts ngeli xesha ukuze ihlangabezane nomlinganiselo we-CCA.

Izinto Ezichaphazela i-CCA

1. Uhlobo Lwebhetri:
   • Iibhetri zeLead-Acid: I-CCA ichaphazeleka ngokuthe ngqo bubungakanani beepleyiti kunye nommandla wonke womphezulu wezinto ezisebenzayo.
   • Iibhetri zeLithium: Nangona zingalinganiswanga yiCCA, zihlala ziphumelela ngaphezu kweebhetri ze-lead-acid kwiimeko ezibandayo ngenxa yokukwazi kwazo ukunika amandla angaguquguqukiyo kumaqondo obushushu aphantsi.
2. Ubushushu:
   • Njengoko ubushushu busehla, iikhemikhali zebhetri ziyacotha, nto leyo enciphisa i-CCA yayo esebenzayo.
   • Iibhetri ezine-CCA ratings eziphezulu zisebenza ngcono kwiindawo ezibandayo.
3. Ubudala kunye nemeko:
   • Ekuhambeni kwexesha, amandla ebhetri kunye ne-CCA ziyehla ngenxa ye-sulfur, ukuguguleka, kunye nokuwohloka kwezixhobo zangaphakathi.

Indlela yokukhetha ibhetri ngokusekelwe kwi-CCA

1. Jonga incwadi yemiyalelo yomnini wakho:
   • Khangela umlinganiselo we-CCA ocetywayo ngumvelisi kwisithuthi sakho.
2. Cinga ngeMozulu yakho:
   • Ukuba uhlala kwindawo ebanda kakhulu ebusika, khetha ibhetri ene-CCA rating ephezulu.
   • Kwimozulu efudumeleyo, ibhetri ene-CCA ephantsi inokwanela.
3. Uhlobo lwesithuthi kunye nokusetyenziswa kwaso:
   • Iinjini zedizili, iilori, kunye nezixhobo ezinzima zihlala zifuna i-CCA ephezulu ngenxa yeenjini ezinkulu kunye neemfuno eziphezulu zokuqala.

Umahluko oPhambili: I-CCA vs Ezinye iiNgcali

• Umthamo Wokugcina (RC): Ibonisa ukuba ibhetri inokuhambisa ixesha elingakanani umbane ozinzileyo phantsi komthwalo othile (osetyenziselwa ukunika amandla izixhobo ze-elektroniki xa i-alternator ingasebenzi).
• Uvavanyo lwe-Amp-Hour (Ah): Imele amandla okugcina amandla ebhetri ngokuhamba kwexesha.
• Ii-Amps ze-Marine Cranking (MCA): Ifana ne-CCA kodwa ilinganiswa kwi-32°F (0°C), nto leyo eyenza ukuba ibe ngqo kwiibhetri zasemanzini.
