Athatha isikhathi esingakanani ukushaja amabhethri angu-18650?

Ibhethri le-18650 liyi-lithium-ion (i-Li-Ion) ekwazi ukuphinda itshajelwe accumulator, cishe ehlala iyisilinda.

18650 ibhethri yokuqala

Ukushaja ibhethri lakho le-18650 okokuqala kungadida kancane. Uma uthola ibhethri lakho, kungcono ukukhokhisa ngokushesha ngaphambi kokulisebenzisa. Bese-ke, lapho usulungele ukuyisebenzisa, qaphela ukukhanya kwenkomba ye-LED eshajani futhi ukhiphe ibhethri lakho ngokushesha lapho lokho kukhanya kucisha (okubonisa ukuthi ukushaja kumile). Lokhu kushajwa kokuqala kufanele kuthathe cishe ihora, ngakho qiniseka ukuthi ugcina ibhethri kushaja isikhathi eside ngokwanele ukuze uqinisekise ukuthi ishajwe ngendlela efanele.

Ungalikhipha kanjani ibhethri le-18650

Isinyathelo 1: Setha okokusebenza

• xhuma i-multimeter ochungechungeni nebhethri ezokhishwa.
• akunandaba ukuthi iyiphi i-terminal eqhubeka iphozithivu nenegethivu, inqobo nje uma ungahlehli i-polarity. (i-probe ebomvu inamathisele ku-pos terminal, i-black probe inamathisele kutheminali ye-neg)
• khuphula isikali se-voltage ukuze ikwazi ukukala okungenani ama-volts angu-5 (noma iphakame ngangokunokwenzeka, ifike ku-7.2 volts)
• qinisekisa ukuthi zonke izinto ezisetshenziswayo zisekelwe phansi ngendlela efanele.

Isinyathelo sesi-2: Setha i-multimeter ukuze ikhiphe

• setha i-multimeter ibe "200 milliamps noma ngaphezulu" (iningi lizoba 500mA) Imodi ye-DC ngokucindezela inkinobho efanelekile ku-multimeter (uma inayo) noma ngokusetha i-multimeter ku-DC voltage bese ubuyela phansi ku-"200 mA oyifunayo. noma ngaphezulu" (okuningi kuzoba ngu-500mA) ocingweni lokudayela.

Isinyathelo sesi-3: Khipha ibhethri

• yehlisa kancane yamanje (ku-multimeter) ize ifunde i-0.2 volts
