Eminyakeni yamuva, ngokuthuthuka okuqhubekayo kobuchwepheshe bezokwelapha, imishini yezokwelapha eyengeziwe idinga ukusetshenziswa kwamaphakethe ebhethri ekhwalithi ephezulu ukuze kuqinisekiswe ukusebenza kwawo okuzinzile nokuqhubekayo. Phakathi kwemishini yezokwelapha, amaphampu okufakelwa angenye yezinto ezivame kakhulu, futhi ukuzinza nokuqina kwawo kubaluleke kakhulu.

Kumaphampu okufakwayo, ukunikezwa kwamandla kungenye yezingxenye ezibaluleke kakhulu, ngakho-ke kuyadingeka ukukhetha iphakethe lebhethri elisezingeni eliphezulu nelisebenza kakhulu. Kulokhu, amaphakethe ebhethri e-nickel-hydrogen ayisinqumo esihle. Amaphakethe ebhethri e-nickel-hydrogen anezinzuzo eziningi, njengempilo ende, umthamo omkhulu, ukuzikhipha okuphansi, nokuzinza okuhle. Lezi zici zingaqinisekisa ukuthi imishini yezokwelapha ingasebenza ngokuzinzile ngenkathi yehlisa izindleko zokunakekelwa kwemishini yezokwelapha.

Ngokuphathelene namapharamitha athile obuchwepheshe, ugesi olinganiselwe wamabhethri ezokwelapha ngokuvamile ungu-14.4V, ongahlangabezana nezimfuneko zamaphampu okufakwayo. Ngaphezu kwalokho, impilo yokusetshenziswa kwamaphakethe ebhethri ye-nickel-hydrogen yinde kakhulu, engahlangabezana nezidingo zemishini yezokwelapha yokuphila kwebhethri.

Ezinhlelweni ezisebenzayo, ngaphezu kokukhethwa kwamaphakethe ebhethri, kuyadingeka futhi ukunaka ukusetshenziswa, ukugcinwa, nokunakekelwa kwamaphakethe ebhethri. Isibonelo, uma usebenzisa amaphakethe ebhethri le-nickel-hydrogen, kuyadingeka ukunaka ukushaja nokukhipha amaphakethe ebhethri ukuze kuqinisekiswe ukusebenza kwawo okuzinzile kwesikhathi eside. Ukwengeza, kuyadingeka futhi ukugcina nokunakekela amaphakethe ebhethri njalo, njengokuhlanza amaphakethe ebhethri kanye nokuhlola ukuthintana kwezixhumi zephakethe lebhethri.

Kafushane, kumishini yezokwelapha njengamaphampu okufakwayo, kubalulekile ukukhetha amaphakethe ebhethri e-nickel-hydrogen asezingeni eliphezulu futhi asebenza kakhulu. Ngokukhetha amaphakethe ebhethri afanelekile kuphela nokunaka ukusetshenziswa kwawo, ukugcinwa nokunakekelwa kwawo, lapho izinto zezokwelapha zingakwazi ukusebenza ngokuzinza nangokuqhubekayo isikhathi eside.
