Ukugcina amabhethri esiqandisini cishe kungenye yezeluleko ezivame kakhulu ozozibona uma kuziwa ekugcineni amabhethri.
Nokho, empeleni asikho isizathu sesayensi sokuthi kungani amabhethri kufanele agcinwe esiqandisini, okusho ukuthi yonke into iwumsebenzi womlomo nje. Ngakho-ke, ingabe kuyiqiniso noma inganekwane, futhi ingabe kuyasebenza noma cha? Ngalesi sizathu, sizophula le ndlela "yokugcina amabhethri" phansi lapha kulesi sihloko.
Kungani amabhethri kufanele agcinwe esiqandisini uma engasetshenziswa?
Ake siqale ngokuthi kungani abantu begcina amabhethri abo esiqandisini kwasekuqaleni. Ukucatshangelwa okuyisisekelo (okungenangqondo ngokombono) ukuthi njengoba izinga lokushisa lehla, izinga lokukhululwa kwamandla liyehla. Izinga lokuzikhipha ngokwalo izinga lapho ibhethri lilahlekelwa ingxenye yamandla alo agciniwe kuyilapho lingenzi lutho.
Ukuzikhipha ngokwakho kubangelwa ukusabela okuseceleni, okuyizinqubo zamakhemikhali ezenzeka ngaphakathi kwebhethri noma kungekho mthwalo ofakiwe. Nakuba ukuzikhipha ngokwakho kungenakugwenywa, intuthuko ekwakhiweni kwebhethri nokukhiqizwa kwehlise kakhulu inani lamandla elilahleka ngesikhathi sokulondoloza. Nakhu ukuthi uhlobo lwebhethri olujwayelekile luphuma lingakanani ngenyanga ezingeni lokushisa legumbi (cishe u-65F-80F):
● Amabhethri e-Nickel Metal Hydride (NiHM): Kuzinhlelo zokusebenza zabathengi, amabhethri e-nickel metal hydride athathele indawo amabhethri e-NiCa (ikakhulukazi emakethe yamabhethri amancane). Amabhethri e-NiHM ayevame ukushajwa ngokushesha, alahlekelwe kufika ku-30% wokushajwa kwawo nyanga zonke. Amabhethri e-NiHM ane-low self-discharge (LSD) akhishwe okokuqala ngo-2005, ngezinga lokukhishwa lanyanga zonke elilinganiselwa kumaphesenti angu-1.25, eliqhathaniswa namabhethri e-alkali alahlwayo.
● Amabhethri E-alkaline: Amabhethri alahlwayo avame kakhulu amabhethri e-alkaline, athengwayo, asetshenziswe aze afe, abese eyalahlwa. Azinze ngendlela emangalisayo, alahlekelwa ngu-1% kuphela wenkokhiso yawo ngenyanga ngokwesilinganiso.
● Amabhethri e-Nickel-cadmium (NiCa): Amabhethri enziwe nge-nickel-cadmium (NiCa) asetshenziswa ezinhlelweni ezilandelayo: Amabhethri okuqala aphinde ashajwa bekungamabhethri e-nickel-cadmium, angasasetshenziswa kakhulu. Azisathengiwe ukushajwa kabusha ekhaya, ngaphandle kokuthi zisasetshenziswa kwamanye amathuluzi kagesi aphathekayo kanye nezinye izinjongo. Amabhethri e-nickel-cadmium alahlekelwa cishe u-10% womthamo wawo ngenyanga ngokwesilinganiso.
● Amabhethri e-Lithium-ion: Amabhethri e-lithium-ion anenani lokuphuma lanyanga zonke elicishe libe ngu-5% futhi avame ukutholakala kumakhompyutha aphathekayo, amathuluzi aphathekayo asezingeni eliphezulu, nakumadivayisi eselula.
Uma kubhekwa amanani okukhishwa, kusobala ukuthi kungani abanye abantu begcina amabhethri esiqandisini ukuze benze izicelo ezithile. Ukugcina amabhethri akho efrijini, ngakolunye uhlangothi, cishe akusizi ngalutho ngokusebenza. Izingozi zingadlula noma yiziphi izinzuzo ezingaba khona ngokusebenzisa indlela ngokwempilo yeshalofu. Ukugqwala nokulimala kungase kubangelwe ukuswakama okuncane ngaphakathi nangaphakathi kwebhethri. Amazinga okushisa aphansi kakhulu angabangela ukuthi amabhethri ahlukumezeke kakhulu. Ngisho noma ibhethri lingonakalisiwe, kuzodingeka ulinde ukuthi lifudumale ngaphambi kokulisebenzisa, futhi uma umoya womkhathi unomswakama, kuzomele uwugcine ungaqongeleli umswakama.
Ingabe amabhethri angagcinwa esiqandisini?
Kuyasiza ukuba nokuqonda okuyisisekelo kokuthi ibhethri lisebenza kanjani ukuze uqonde ukuthi kungani. Sizonamathela kumabhethri ajwayelekile e-AA kanye ne-AAA ukuze sigcine izinto zilula – awekho amabhethri e-smartphone noma aphathekayo lapha.
Okwesikhashana, ake sihambe kwezobuchwepheshe: amabhethri akhiqiza amandla ngenxa yokusabela kwamakhemikhali okubandakanya izinto ezimbili noma ngaphezulu ngaphakathi. Ama-electron ahamba esuka kwenye itheminali eya kwelandelayo, edlula kugajethi awanika amandla lapho ebuyela kweyokuqala.
Ngisho noma amabhethri engaxhunywanga, ama-electron angase abaleke, ehlise umthamo webhethri ngenqubo eyaziwa ngokuthi yi-self-discharge.
Esinye sezizathu ezibalulekile ezenza abantu abaningi bagcine amabhethri esiqandisini ukwanda kokusetshenziswa kwamabhethri aphinde ashajwe. Amakhasimende abe nesipiliyoni esibi kuze kube yiminyaka eyishumi edlule, futhi iziqandisi zaziyisixazululo sebhande losizo. Esikhathini esifushane nje senyanga, amabhethri athile ashajwa kabusha angalahlekelwa afinyelela ku-20% kuya ku-30% womthamo wawo. Ngemva kwezinyanga ezimbalwa eshalofini, base befile futhi badinga ukushajwa ngokuphelele.
Ukuze kuncishiswe ukuncipha okusheshayo kwamabhethri angaphinda ashajwe, abanye abantu bahlongoza ukuwagcina esiqandisini noma ngisho nasefrijini.
Kulula ukubona ukuthi kungani isiqandisi singaphakanyiswa njengesixazululo: ngokunciphisa ukusabela kwamakhemikhali, kufanele ukwazi ukugcina amabhethri isikhathi eside ngaphandle kokulahlekelwa amandla. Ngokujabulisayo, amabhethri manje angakwazi ukugcina ukushajwa okungamaphesenti angu-85 kuze kube unyaka ngaphandle kokuba iqhwa.
Ulephula kanjani ibhethri elisha lomjikelezo ojulile?
Kungenzeka ukuthi uyazi noma ungazi ukuthi ibhethri ledivayisi yakho ephathekayo lidinga ukugqekezwa. Uma ukusebenza kwebhethri kwehla ngalesi sikhathi, ungesabi. Amandla nokusebenza kwebhethri lakho kuzoba ngcono kakhulu ngemva kwesikhathi sokunqamuka.
Isikhathi sokuqala sokugqekeza samabhethri avaliwe ngokuvamile singu-15-20 aphumayo futhi aphinde ashajwe. Ungathola ukuthi ibanga lebhethri lakho lingaphansi kwalokho okwakufunwe noma okuqinisekisiwe ngaleso sikhathi. Lokhu kwenzeka kaningi. Isigaba sokunqamuka senza kancane kancane izindawo zebhethri zisebenze ukuze zibonise amandla aphelele edizayini yebhethri ngenxa yesakhiwo esiyingqayizivele kanye nomklamo webhethri lakho.
Ibhethri lakho lingaphansi kwezidingo ezijwayelekile zokusetshenziswa imishini yakho yokuhamba ngesikhathi sokugqekeza. Inqubo yokugqekeza ivamise ukuqedwa ngomjikelezo ogcwele wama-20 webhethri. Injongo yesigaba sokuqala sokugqekeza ukuvikela ibhethri ekucindezelekeni okungadingekile phakathi nemijikelezo embalwa yokuqala, ukuyivumela ukuthi imelane nokukhipha amanzi kakhulu isikhathi eside. Ukukubeka ngenye indlela, unikela ngenani elincane lamandla ngaphambili ukuze uthole ukuphila okuphelele kwemijikelezo eyi-1000-1500.
Ngeke uthuke uma ibhethri lakho elisha sha lingasebenzi ngendlela obulindele ngayo ngaleso sikhathi ngoba uyaqonda ukuthi kungani isikhathi sokungena sibaluleke kangaka. Kufanele ubone ukuthi ibhethri selivuleke ngokugcwele ngemva kwamaviki ambalwa.
