Mangaki ama-mAh Ibhethri ye-Lithium AA?

Ibhethri ye-Lithium AA ibhethri elifakazelwe njengebhethri elingcono kakhulu lanamuhla kanye nenketho ephezulu yamathoshi namalambu aphambili. Iphinde ibe nezici ezimbalwa ezifana nokungabi nawo umthelela wenkumbulo, izinga elingcono lokuzikhipha, kanye nebanga lokushisa elibanzi lokusebenza. Ayinazo izinto zamakhemikhali ezidala ukuwohloka noma ukuvuza lapho zishiywe isikhathi eside zingasetshenzisiwe. Iphinde ibe nempilo ende yokugcina futhi ingagcinwa iminyaka emi-5 ngaphandle kokulahlekelwa umthamo wayo omkhulu.

Mangaki ama-mAh Ibhethri ye-Lithium AA?

Amabhethri e-Lithium amayelana nomthamo. Zikalwa ngokuthi mangaki ama-mAh (ama-milliamp ngehora) eziwakhiphile. Lokhu kucacisa ukuthi zihlala isikhathi esingakanani zikhokhiswa. Uma inombolo iphakeme, iqhubeka isikhathi eside; yilokho kuphela okukhona kukho. Ukuze unqume ukuthi i-mAh eyodwa yamandla izothatha amahora amangaki, hlukanisa u-60 ngama-milliamp (mA). Isibonelo, uma unethoshi elinamabhethri angu-200 mA lisebenza ihora, lingadinga u-100mAh.

Ama-Hobbyists avame ukuba nentshisekelo kumabhethri e-lithium AA aphezulu. Abathanda ukuzilibazisa bayawajabulela lawa mabhethri ngoba anesisindo esincane futhi anomthamo omuhle kakhulu osebenza ngamanani aphakathi nendawo. Alula kakhulu kunamaseli e-alkaline futhi anganikeza umthamo ophindwe kathathu noma cishe amahora angama-milliamp angu-8X ngedola ngalinye uma kuqhathaniswa namaseli e-alkaline! Amaseli e-Lithium AA anamandla amakhulu angaletha kufika ku-2850 mAh nangaphezulu, njengeseli ye-Energizer L91 Lithium noma amabhethri aphinde ashajwa i-Lithium-Ion.

Amabhethri e-alkaline avamile ane-voltage ebizwa ngokuthi i-1.5 Vdc; nokho, ijika lazo lokukhipha eliwumugqa liqala cishe ku-1.6 volts futhi liphele cishe ku-0.9 volts ngaphansi komthwalo - okungaphansi kwamazinga amukelekayo ezisetshenziswa zikagesi eziningi. Njengomphumela walokho, ama-elementi esekethe engeziwe ayadingeka ukuze kugcinwe amandla kagesi adingwa idivayisi egijima iphakethe lebhethri le-Alkaline ezingeni eliklanywe ngalo, okusala kancane ukuze kusetshenziswe izinto zikagesi ezakhelwe ngaphakathi zedivayisi yakho.

Uyinweba Kanjani Impilo Yomjikelezo Webhethri ye-Lithium AA?

Amabhethri e-Lithium anempilo yomjikelezo omude kunayo yonke yanoma ibuphi ubuchwepheshe bebhethri obushajekayo obutholakalayo njengamanje. Iseli le-AA elisha, elingasetshenzisiwe lizoba nomthamo ojwayelekile phakathi kuka-1600mAh ngeseli yekhwalithi evamile kanye no-2850mAh+ weseli esebenza kahle kakhulu ye-Lithium-Ion enomthamo owengeziwe ofika ku-70% uma kuqhathaniswa ne-Alkaline entsha efanayo.

Amabhethri angasetshenzisiwe angashiywa emaphaketheni awo eshajwe kancane noma aphelele isikhathi eside ngaphandle kokushona. I-PowerStream Technologies iqinisekisa ukuthi amabhethri ayo azogcina u-85% womthamo wawo iminyaka emi-5, okuyinto ehamba phambili ekilasini - ikakhulukazi uma kubhekwa ukuthi la maseli abiza kangakanani. Ezinye izici ezifana nokushisa, ukubanda, nokuswakama akuthinti ngokoqobo amabhethri e-Lithium-Ion.

Amabhethri e-lithium awekho ngaphansi "komphumela wenkumbulo" amabhethri e-NiCd ne-NiMH ahlushwa yiwo futhi awadingi ukushajwa ngokugcwele ngaphambi kokuwashajwa ukuze andise impilo yawo. Ukulungiswa okufanelekile kwamaseli e-lithium kwenziwa ngokufaka umthwalo wokukhipha okumaphakathi cishe imizuzu emi-5 bese uwashaja aze afinyelele umthamo ogcwele. Uma eshajwe ngale ndlela, Amabhethri e-Lithium azohlala isikhathi eside kakhulu kunalapho eshajwe ngokusobala noma lapho efakwe esimweni njalo.

Ukukhishwa okuyingxenye kungaba nomthelela ekulahlekelweni kwempilo yomjikelezo, ikakhulukazi ngamakhemikhali asekelwe ku-nickel anamandla athile aphansi kakhulu kunekhemistri ye-lithium, ngakho-ke zama ukugwema izinhlelo zokusebenza lapho ukhipha amandla ephaketheni lakho lebhethri ngokukhuphuka okuncane njengezinhlelo zokusebenza zethoshi eziphathwayo, isibonelo.

Isiphetho

Amabhethri e-Lithium ahlinzeka ngomthamo ophezulu kakhulu (mAh) kunamaseli e-alkaline futhi anganikeza amahora afinyelela kwamathathu ama-milliamp amakhulu ngedola ngalinye elidingwa amadivaysi akhipha amanzi amaningi. Futhi banomjikelezo omude kakhulu wanoma ibuphi ubuchwepheshe bebhethri obushajekayo obukhona namuhla. Ngaphezu kwalokho, Amabhethri e-Lithium awekho ngaphansi "komphumela wenkumbulo" amabhethri e-NiCd ne-NiMH ahlushwa yiwo.
