AAA roj teeb: hom thiab cov yam ntxwv

Technology ntawm cov niaj hnub ntiaj teb no yuav txo thiab tsis muaj nyob ntawm tej. Qhov no ua rau lub fact tias nyob rau hauv xyoo tsis ntev los ntau thiab ntau muaj ntau yam ntawm pab kiag li lawm thiab cov khoom siv rau khoom noj khoom haus uas siv "AAA" hom roj teeb. Xws li muaj lub tsev yuav luag txhua txhua ib ntawm peb. Qhov no wireless nas, shaving machines, tej thaj chaw deb tswj TV thiab DVD, handheld lub suab recorders, suab players, thiab lwm yam

Roj teeb "AAA" vim hais tias ntawm nws me me luaj li cas yog feem ntau hu ua "mizinchikovymi" los yog "minipalchikovymi". nram qab no cim kuj siv tau rau labeling khoom noj ntawm no hom: LR3, R3, LR03 (IEC) thiab R03. Thaum koj xaiv tus cell rau koj gadget yuav tsum xub xyuam xim rau cov hom ntsha siv, txij li thaum nws muaj feem xyuam rau lub peev xwm, ntev ntawm kev ua hauj lwm thiab muaj peev xwm rau recharge.

Nyob ntawm seb nws muaj pes tsawg leeg, "AAA" roj teeb yog muab faib ua tej saline, alkaline (alkaline) thiab lithium.

Khoom siv fais fab, nyob rau hauv uas lub ntsha ntsev yog siv, tsim los rau cov uas tsis muaj load thiab feem ntau siv nyob rau hauv ntoos, hluav taws xob ntsuas kev kub txais, thiab tej thaj chaw deb tswj. Lawv yog cov uas pheej yig tshaj thiab luv luv-lived. Yuav kom paub qhov txawv lawv los ntawm lwm yam uas tau tsis tuaj kawm ntawv ntawm cov prefix L mus labeling, e.g. R3, R6, thiab tsis muaj nqi (raws li hais saum toj no).

Alkali (alkaline) roj teeb "AAA" nyob ib nrab txoj hauj lwm. Lub ntsha lawv siv poov tshuaj hydroxide, thiab qhov no yog lub ntsiab qhov txawv ntawm lub saline ntsiab. Tshuaj lom neeg tshua tshwm sim nyob rau hauv xws qhov chaw nrog ntau dua cov kev ceev. Qhov no muaj txhawb rau ib tug zoo dua tam sim no rov qab. Lawv pab lawm thiab haum rau cov khoom nrog ib tug nruab nrab theem ntawm lub zog noj: audio players, PDAs, radios, thiab lwm yam Tsis zoo li lwm yam uas lawv yuav tsum nyob rau hauv lo lus «alkaline» thiab muaj cov tsab ntawv L nyob rau hauv labeling.

Qhov zoo tshaj plaws hom lithium roj teeb "AAA" hom. Lawv muaj lub kawg nrog kuj thiab coos tau pab lub neej. Lawv yog pab rau pab kiag li lawm nrog intensive zog noj: cov khoom ua si, LED teeb, lwm yam

Yog hais tias tus ntaus ntawv yog siv feem ntau txaus, ces ib qho zoo heev lwm "minipalchikovym" alkaline thiab lithium hlwb ua rechargeable roj teeb "AAA" hom. Nrog lub charger xws qhov chaw yuav sam ib tug nruab nrab ntawm txog ib txhiab lub sij hawm. Peev Xwm rechargeable roj teeb yog feem ntau qhia nyob rau hauv ampere-teev. Cov kis tam sim no tau txais cov nram qab no hais:

• Li-pol (Li-polymer);
• Li-pol (Li-ion);
• NiMH (Nickel Hlau Hydride);
• NiCd (npib tsib xee-cadmium).

Txhua yam ntawm lawv nws muaj nws tus yam ntxwv. Yog li ntawd, NiMH-roj teeb yog rhiab heev rau overcharging, thiab cov chaw ua hauj lwm ntawm lithium thiab kuj nyob rau hauv lub voltage thiab kub. Qhov chaw ntawm hom NiMH thiab NiCd muaj thiaj li hu ua "nco nyhuv", uas yog los txo cov capacitance thaum them lub roj teeb yog tsis pom. Nyob rau hauv tas li ntawd mus rau cov ob hom yog yus muaj los ntawm appreciable self-paug, i.e. xwb tsis txawm thaum kaw, thaum lub ntaus ntawv yog muab tua. Cadmium roj teeb thiab txawm muaj tsis muaj zog noj, zoo mas frosts thiab yuav mas txawm luv luv circuits.

Yog li ntawd, cov kev xaiv hwj chim qhov twg los "AAA" hom tawg ntho nyob raws li qhov ntaus ntawv nyob rau hauv uas nws yuav tsum tau siv thiab tej yam kev mob ntawm lub neej tom ntej hauj lwm. Pes tsawg ib yam thaum yuav yam khoom uas koj yuav tsum them sai sai mus rau lub hom thiab txee lub neej.
