Ukuba uhlala unesimo xa kunomzuzu ongaphelelanga ukhamera engasebenzi, ngoko lixesha lokutshintsha ibhetri eqhelekileyo enebhethri. Umthombo ogunyazisiweyo wamandla osetyenziswa ngokubanzi kwimpilo yemihla ngemihla - ekulawuleni kude, imouse yekhompyutheni engenakwii-desktop, nakwii-desktop kwikhompyutha. Uhlobo oluphambili kwiibhetri eziqhelekileyo luyinto yokuhlawula ezininzi. Ngoko, siya kukuxelela malunga neempawu zeebhetri zomnxeba, kwakunye neendlela ezikhethiweyo.
Ziziphi - iibhetri ezihlawulelwayo?
Ukuba sithetha malunga nendlela yokujonga ibhetri yebhetri, ngokobubukeka bahluke kakhulu kwiibhetri eziqhelekileyo. Le yileyilinda efanayo, ububanzi bayo abudluli kwi-13,5 mm. Ukukwahlula iibhetri ezivela kwiibhetri ziya kunceda ukubhaliswa kokuqala "Ukuhlawuleka", oko kukuthi, "kutshaywa kwakhona". Zibhalwe kwakhona nge-AA, ngokungafani neibhetri ezincinci zeminwe ezibhalwe ngeAAA.
Iibhethridi ezingapheliyo ze-Nickel-Metal Hydride
Uninzi ngokuqhelekileyo kwiindawo zokuthengisa unokufumana iibhetri ze-nickel zethusi zamanzi. Iinjongo zazo eziphambili zi:
- indleko ephantsi;
- ukusilela "umphumo wokukhumbula";
- amandla amakhulu.
Kule meko, iibhetri zolu hlobo nazo zinokungalungi, oku:
- inokwenzeka yokutshisa xa uhlawula;
- uvakalelo kumashishini aphakamileyo aphantsi;
- ukubonakala kokuzikhupha.
Iibhetri ze-Nickel-cadmium
Olunye uhlobo lweebhetri zeminwe elayishwayo - iibhetri ye-nickel-cadmium - ixabiselwa:
- inani elikhulu lokubuyisela (ukuya kwiwaka), ngaphandle kokuba zisetyenziswe ngokuchanekileyo;
- ukukwazi ukusebenzisa kuzo zonke izimo zemozulu;
- ukugcinwa kwentlawulo ixesha elide;
- indleko ephantsi.
Kule meko, iibhetri, ngelishwa, iingxaki ezingundoqo:
- Eyona nto ibaluleke kakhulu into ebizwa ngokuthi "umphumo wememori". Ngokuqhelekileyo kwenzeka xa uphinda ukhupha iibhetri phakathi, uze uhlawulwe kwakhona. Ngenxa yoko, ngokuqhelekileyo ayinelisekanga xa umthombo wamandla unokwenza ingxelo ngokugqithiseleyo ukukhutshwa kwayo ngokupheleleyo. Yingakho ngaphambi kokuba uzihlawule umele uqale ukhulule ngokupheleleyo.
- Ngaphezulu, iibhentri zomnxeba zomnxeba we-nickel-metal ziyakwazi ukuzikhupha, kwaye zisoyika ukuhlaziya.
Iibhetri ze-lithium-ion
Iibhetri ze-lithium-ion azikho phantsi "komphumo wokukhumbula", zinokuhlawulwa ngaliphi na ixesha. Ukufaneleka kwalolu hlobo lwebhethri kungaquka:
- ukungabikho kokuzikhupha;
- umthombo wesistim ohlawulelwayo (amaxesha angama-500-700);
- isibonakaliso esikhulu samandla.
Ngelishwa, kukho iintsilelo. Iibhetri ze-lithium-ion zibuhlungu kakhulu:
- kumaqondo aphezulu;
- kwiintsipho zamandla.
Iibhetri ezingenasiphelo - ezingcono?
Iindidi ezahlukeneyo zamabhethri ahlaziyiweyo ngamanye amaxesha ukhetha ukukhetha umthombo wamandla nzima. Ukuba ufuna iibhetri kwifowuni oceba ukuyisebenzisa ngamanye amaxesha, kungcono ukukhetha iibhetri ye-nickel-metal hydride engenzi ngaso "imemori yempembelelo", ngoko ke ayidingi ukukhutshwa ngokupheleleyo. Qaphela ukuba akunzima. Ukumakishwa kwezi bhetri zomunwe ezithengiswayo yi- Ni-MH . Ngako oko, ukuba izixhobo ezisetyenziswa ngokuqhelekileyo zenza ingqiqo ukuthenga i-lithium-ion okanye i-nickel-cadmium ebizwa ngokuba yi-Li-ion, yesibini-ye-Ni-Cd.
Xa ukhetha ibhetri elungileyo, lalela ingqalelo amandla alo. Ephakamileyo, ngakumbi, tshela, unokuthatha iifoto. Xa kuthengiswa kukho izinto ezivela kwi-650 ukuya kwi-2700 mA / h. Qaphela ngexesha elinye eliphakamileyo umthamo, ixesha elide ibhetri lihlawulwa. Ukuthetha ngabavelisi, iimveliso ezisuka ku-Panasonic Eneloop, i-GP, i-Duracell, i-Varta, i-Energizer, i-Kodak, i-Sony nabanye bathandwa.
