Uma uvame ukubhekana nesimo uma kungenakwenzeka kakhulu ikhamera engasebenzi, sekuyisikhathi sokuthatha amabhethri evamile ngamabhethri. Kuyinto imithombo ethandwayo yamandla esetshenziselwa kakhulu ekuphileni kwansuku zonke - ekulawuleni okude, i-computer engenantambo yekhompuyutha, kwiwashi ledeskithophu ngisho nasezintweni zezingane. Umehluko omkhulu ovela emabhethri avamile kungenzeka ukushaja okuningi. Ngakho-ke, sizokutshela mayelana nokuzikhethela kwamabhethri alayishiwe, kanye nama-nuances okukhethayo.
Ziyini - amabhethri avuselelekayo?
Uma sikhuluma ukuthi singabheka kanjani amabhethri ebhethri, bese sibukeka behluke kancane kumabhethri avamile. Leli cylinder efanayo, elingamamitha ayi-13.5 mm. Ukuhlukanisa amabhethri avela kubhethri kuzosiza ukubhaliswa kokuqala "Okuvuselekayo", okungukuthi, "okuvuselelwa kabusha". Zibuye zibhalwe nge-AA, ngokungafani namabhethri amancane omunwe okuthiwa i-AAA.
I-Nickel-Metal Hydride I-Batteries engakwazi ukuvuselelwa
Ngokuvame kakhulu ezitolo ungathola amabhethriri e-nickel-metal hydride. Izinzuzo zabo eziyinhloko yizi:
- izindleko eziphansi;
- ukungabi "nomthelela wememori";
- amandla amaningi.
Kulesi simo, amabhethri alolu hlobo nawo anezimo ezimbi, okungukuthi:
- kungenzeka ukushisa lapho ushaja;
- ukuzwela emazingeni okushisa aphezulu naphansi;
- ukubonakala kokuzikhandla.
Amabhethri e-Nickel-cadmium
Olunye uhlobo lwamabhethri wokunwetshwa kabusha ngomunwe - amabhethri e-nickel-cadmium - alinganiswa nge:
- inombolo enkulu ye-recharges (kuze kube yizinkulungwane), uma nje isetshenziswe kahle;
- ikhono lokusebenzisa kuzo zonke izimo zezulu;
- ukulondolozwa kwentela isikhathi eside;
- izindleko eziphansi.
Kule nkinga, amabhethri, ngeshwa, ukuphazamiseka okuphawulekayo:
- Okubaluleke kunazo zonke yilokho okuthiwa "umphumela wememori". Kuvame kwenzeka uma uphinde ukhulule amabhethri phakathi, bese ukhokhiswa kabusha. Ngenxa yalokho, ngokuvamile ayinelisekile uma umthombo wamandla ungabika ukukhishwa kwawo ngokugcwele ngamanga. Yingakho ngaphambi kokuwashaja kumele uqale ukukhipha ngokuphelele.
- Ngaphezu kwalokho, amabhethridi omunwe we-nickel-metal ayakwazi ukuzikhandla, futhi asaba ukuvuselelwa.
Amabhethri e-lithiamu-ion
Amabhethri e-lithiamu-ion ayitholakali nhlobo "nomphumela wokukhumbula", angakhokhiswa nganoma isiphi isikhathi. Ukufaneleka kwaloluhlobo lwebhethri kungabuye kufake:
- ukungabi khona kokuzikhishwa;
- isilinganiso sesisetshenziswa sokufaka kabusha (izikhathi ezingu-500-700);
- isibonakaliso esikhulu somthamo.
Ngeshwa, kunamaphutha. Amabhethri e-lithium-ion azwela kakhulu:
- emazingeni okushisa aphezulu;
- kumaconsi amandla.
Amabhethri angenasici - angcono?
Ama-batteries amaningi avuselelekayo ngezinye izikhathi enza kube nzima ukukhetha umthombo wamandla. Uma udinga amabhethri ukuze uthole idivaysi oyilungiselela ukuyisebenzisa ngezikhathi ezithile, kungcono ukunikeza izintandokazi zamabhethridi e-nickel-metal hydrde angenzi ngesimo "sememori", ngakho-ke akudingeki ukuba akhululwe ngokuphelele. Qaphela ukuthi akunzima. Ukumaketha kwalawa mabhethri akhokhelwa kabusha yi- Ni-MH . Ngakho-ke, ngoba imishini esetshenziswa kaningi kuwukuhlakanipha ukuthenga i-lithium-ion noma i-nickel-cadmium ebizwa ngo-Li-ion, owesibili - i-Ni-Cd.
Lapho ukhetha ibhethri elungile, qaphela amandla ayo. Okuphakeme, nakakhulu, uthi, ungathatha izithombe. Kuthengiswa kukhona ukuhlukahluka kusuka ku-650 kuya ku-2700 mA / h. Qaphela ngesikhathi esifanayo ukuthi ngaphezulu kwamandla, isikhathi eside ibhethri siyakhokhiswa. Ekhuluma ngabakhiqizi, imikhiqizo evela ku-Panasonic Eneloop, i-GP, i-Duracell, i-Varta, i-Energizer, i-Kodak, i-Sony nabanye bayathandwa.
