Lub hom phiaj ntawm 18650 lithium batter yog dab tsi?
1. Lub neej ntawm 18650 lithium roj teeb yog theoretically ntau tshaj 500 lub voj voog ntawm kev them nyiaj.Nws yog feem ntau siv nyob rau hauv lub teeb muaj zog teeb nyem, headlamp, mobile kho mob, thiab lwm yam.
2. Nws kuj tuaj yeem ua ke.Kuj tseem muaj qhov sib txawv ntawm nrog thiab tsis muaj lub rooj tsavxwm.Qhov sib txawv tseem ceeb yog qhov kev tiv thaiv ntawm lub rooj tsavxwm yog tshaj tawm, tshaj tawm thiab cov nqi dhau tam sim no, txhawm rau tiv thaiv lub roj teeb kom tsis txhob raug khawb vim kev them nyiaj dhau los lossis hluav taws xob huv heev.
3. 18650 tam sim no feem ntau yog siv rau hauv phau ntawv roj teeb, thiab qee lub teeb pom kev zoo kuj tseem siv tau.Tau kawg, 18650 muaj kev ua tau zoo heev, tsuav yog tias lub peev xwm thiab qhov hluav taws xob tsim nyog, nws zoo dua li cov roj teeb uas ua los ntawm lwm cov ntaub ntawv, thiab nws kuj yog ib qho ntawm cov roj teeb lithium nrog cov nqi siab.
4. Teeb nyem, MP3, interphone, xov tooj ntawm tes.Ntev npaum li qhov hluav taws xob nyob nruab nrab ntawm 3.5-5v, cov khoom siv hluav taws xob tuaj yeem txawv ntawm No. 5 roj teeb.18650 txhais tau hais tias txoj kab uas hla yog 18 hli thiab qhov ntev yog 65 hli.Cov qauv ntawm No. 5 roj teeb yog 14500, txoj kab uas hla yog 14 hli thiab qhov ntev yog 50 hli.
5. Feem ntau, 18650 roj teeb tau siv dav hauv kev lag luam, thiab maj mam qhia rau cov tsev neeg pej xeem.Nyob rau hauv lub neej yav tom ntej, lawv yuav txawm tsim thiab faib rau mov cookers, induction cookers, thiab lwm yam raws li backup fais fab mov.Lawv feem ntau siv rau hauv phau ntawv roj teeb thiab lub teeb nyem siab kawg.
6. 18650 tsuas yog qhov loj thiab qauv ntawm roj teeb.Raws li hom roj teeb, nws tuaj yeem muab faib ua 18650 rau lithium ion, 18650 rau lithium hlau phosphate thiab 18650 rau nickel hydrogen (tsis tshua muaj).Tam sim no, cov 18650 ntau tshaj lithium ion, uas yog dav siv nyob rau hauv ntau yam lag luam.18650 lithium-ion roj teeb yog qhov zoo tshaj plaws thiab ruaj khov nyob hauv lub ntiaj teb, thiab nws txoj kev lag luam tseem yog cov thev naus laus zis ntawm lwm cov khoom siv lithium-ion.
