Elishajekayo amabhethri umunwe - indlela ukukhetha?

Ninazo amawashi? Noma flashlight? Noma, esikude TV? Zonke lezi zinto abe umthombo olulodwa amandla abo - kungcono elishajekayo amabhethri umunwe. Akulula kanjalo ukuba siphume ukuthenga ibhethri esifanele. Ungakhetha wakhe, yebo, ku ngokubukeka kwakhe, ngegama, intengo, noma ukuthatha elifana ukuthi ngaphambili e lisebenze. Nokho, amadivayisi umsebenzi izinga ezifana amabhethri elishajekayo umunwe, wena Kufanele bazi begodu bazwisise kokungafani okukhulu ngohlobo olulodwa ukusuka kwenye. Ngakho uqala kanjani?

Okokuqala, kufanele siqonde ukuthi usawoti elishajekayo amabhethri umunwe kungaba amakhono ehlukene kanye nobukhulu obuhlukahlukeneko. Umklamo elula abo aphansi: Ngakolunye uhlangothi i-anode, ngakolunye - a cathode kanye electrolyte elise phakathi kwazo.

Wona umumo cylindrical idivayisi ezifana amabhethri umunwe ikhethwa akwenzekanga ngephutha. A dengezi ewumngcingo sinekhono esifanayo has a Coefficient ephakeme ka ukushabalalisa ukushisa kanye ukumelana omncane. Lebula lezi amadivaysi ngaphansi kwemithetho ye-R incwadi kanye nenombolo (isib R11).

Lezi zindlela esiyinhloko Ukukhetha Amadivayisi ezifana amabhethri penlight Izimo zokusebenza. Lokhu kungaba umthwalo omkhulu (ngesikhathi samanje 0.2 Amps), eliphakathi (0.1 Amps) nabancane (esingaphansi 0.01 Amps). imithwalo esindayo kungabonwa uma usebenzisa amabhethri flashlight, amakhamera, ingcindezi Izikali nabadlali. Isilinganiso asebenza amathoyizi zezingane. Small umthwalo sici amawashi. Ngokungangabazeki, zonke lezi zimo, ibattery ebe eziphatha ngendlela eyehlukile.

Kuyadingeka ukukhumbula ithonya ngqo imvelo ukusebenza idivayisi ezifana elishajekayo amabhethri umunwe. Ngezinye ongaphakeme lokushisa electrolyte le conductivity incipha, kunciphe nomthamo umthombo. Jwayelekile lokushisa ibhethri lihamba lisuka degrees zero mahlanu. Ibhethri kakhulu kakhulu kukhishelwa ekuqaleni isitoreji. Ngakho-ke akufanele ukuthenga amabhethri ebusika ngaphandle.

Amabhethri zingahlukaniswa zibe lithium, ane-alikhali futhi nosawoti (bayehluka by uhlobo electrolyte zabo).

The main izakhi ethile usawoti ingashiwo nokwehlisa voltage yokusebenza phakathi nesikhathi khulula. Ukusebenza nomthamo ibhethri kuyoba ephakeme kunaleyo imithwalo medium and okusezingeni eliphezulu nge isimo ngakanye. Ngokuvamile, uyakwazi ukubona ukuthi lapho kukhishelwa ngokugcwele electrolyte ibhethri ayozithola kuwo. Lolu hlobo amabhethri penlight yisona esikhulunywa abantu abaningi ngenxa cheapness yayo.

amabhethri ane-alikhali okuhlala ngaphezulu. Basebenza kahle ngaphansi kwamazinga okushisa aphansi kanye nokugcina kangcono izakhiwo zabo ngesikhathi Postojna. Ngokwemvelo, ngentengo yabo iyoba kakhulu kunakunoma usawoti.

Futhi ekugcineni, kumelwe ishiwo lithium amabhethri. Ziyakwazi kuqhathaniswa eqolo (ezibizayo alikhali, nosawoti), kodwa has a okukhulu amandla izici, okusezingeni eliphezulu yokusebenza voltage, ukuzinza, anhlobonhlobo osenyameni imisinga kanye amazinga okushisa ezisebenza, ukuphila isikhathi eside isitoreji.
