Umuzwa wokukhethwa kwebhethri leisibani esikhulu

Sekuphele iminyaka engu-20 ngaphumela ngaphandle ngo-1998 ngathenga isikhwama sokuqala sokuqwala izintaba i-vaude70 litre.Kule minyaka engama-20, ngisebenzise izinhlobo ezingaphezu kweziyi-100 zamathoshi amalambu.Kusukela ekuthengeni imikhiqizo eqediwe kuye ekuzihlanganiseni, nginezidingo ezihlukahlukene.Ekugcineni, ngigcina kuphela amathoshi amalambu angaphezu kweshumi nambili.Manje ngikhuluma nje ngolwazi lwami ekukhetheni ibhethri.
Amalambu anezidingo ezihlukene zokukhetha amabhethri ngokuya ngendawo yesevisi.
Isibonelo, ukuhamba nje noma ukugijima emigwaqweni yasemadolobheni nasezindaweni zasemakhaya, isikhathi sokusebenzisa asiside, futhi izinga lokushisa le-ambient ngeke libe phansi kakhulu.Njengoba ibhethri lingathengwa futhi lishintshwe nganoma yisiphi isikhathi, i-AAA, AA namabhethri e-alkaline carbon angasetshenziswa.Ngenxa yokuthi akuyona indawo enzima, ibhethri ingashintshwa futhi ishajwe kabusha nganoma yisiphi isikhathi.Ekuphishekeleni ukukhanya, abantu abaningi bakhetha izibani ze-3AAA.

Ebusika, amabhethri asezingeni eliphansi angakhetha amabhethri e-lithium noma amabhethri e-nickel metal hydride.Phakathi kwazo, izinga lokushisa eliphansi lebhethri le-Ni MH lingasetshenziswa ku-minus 40 degrees!Nokho, amandla ebhethri ye-Ni MH enezinga eliphansi lokushisa aphansi uma kuqhathaniswa.
Uma udinga ukuthatha umgwaqo wezintaba, ama-lumens angu-100-200 ayisisekelo.Uma kungenjalo, kunzima ukubona indawo yomgwaqo ngokucacile.Indawo yomgwaqo yasehlathini, ikakhulukazi indawo yomgwaqo enamaqabunga abolile kakhulu futhi imanzi kancane, ngivame ukusebenzisa ama-lumens angu-350-400 ukuze ngikhanyise, futhi ngisebenzise ngisho nama-lumens angaba ngu-600 ukuze kube nzima futhi kunzima ukuhamba.Uma kungenjalo, ukusebenzisa ama-lumens angaba ngu-150 ukukhanyisa kuyohlale kungena odakeni.

Ngenxa yesidingo sokukhanyisa, ukuze kuqinisekiswe amandla okukhanyisa, kunezidingo zebhethri lelambu.Ngakho-ke, ukuze kuqinisekiswe isidingo sokukhanyisa, kunconywa ukusebenzisa i-3AA noma i-4AA ukuze unikeze isidingo esanele.Ngokuqondene ne-3AAA, KULUNGILE ukuqhuma ama-lumens angu-200 ngesikhathi esifushane, futhi isikhathi sokukhanyisa okuqhubekayo sama-lumens angu-200 ngesigamu sehora asikwazi ukuhlinzekwa, futhi ukukhanya kuzokwehla kakhulu.Phela, umthamo webhethri uyanquma.

Mayelana nokusebenza kokugcinwa kwamandla okushisa okuphansi, amabhethri e-alkaline ahlulekile ngokuphelele, amabhethri e-nickel hydrogen ayafana namabhethri e-lithium, kanti amandla - 30 degrees angaphansi kuka-50%.

Uma kunzima ukuthola amandla okukhanyisa ngaphandle isikhathi eside, kunconywa ukusebenzisa i-18650 lithium ibhethri powered headlamp flashlight.
