Yawanci, 3.7vbatirin lithiumyana buƙatar "allon kariya" don caji fiye da kima da kuma fitar da ruwa fiye da kima. Idan batirin ba shi da allon kariya, zai iya amfani da ƙarfin caji na kimanin 4.2v kawai, saboda ƙarfin cikakken caji mafi kyau na batirin lithium shine 4.2v, kuma ƙarfin lantarki ya wuce 4.2v. Lalacewar batirin, yayin caji ta wannan hanyar, ya zama dole a sa ido kan yanayin batirin a kowane lokaci.
Idan akwai allon kariya, za ka iya amfani da 5v (ana iya amfani da 4.8 zuwa 5.2), za a iya amfani da USB5v na kwamfuta ko kuma caja ta 5v na wayar hannu.
Ga batirin 3.7V, ƙarfin yanke caji shine 4.2V, kuma ƙarfin yanke fitarwa shine 3.0V. Saboda haka, lokacin da ƙarfin wutar lantarki na buɗewa na batirin ya yi ƙasa da 3.6V, yakamata ya sami damar caji. Ya fi kyau a yi amfani da yanayin caji na wutar lantarki mai 4.2V akai-akai, don haka ba kwa buƙatar kula da lokacin caji. Caji da 5V yana da sauƙin caji fiye da kima kuma yana haifar da haɗari.

1. Cajin iyo. Yana nufin caji yayin aiki akan layi. Wannan hanyar galibi ana amfani da ita a lokutan samar da wutar lantarki. Idan ta yi ƙasa da volt 12, ba za a iya caji ba, kuma idan ta yi yawa, za ta shafi aikin da'irar. Saboda haka, lokacin da cajin iyo ke aiki, ƙarfin lantarki shine volt 13.8.

2. Cajin da za a yi a zagaye. Yana nufin caja cikakken caji don dawo da ƙarfin baturi. Idan aka yi caji sosai, ba a cire caja don aunawa ba. Gabaɗaya, yana kusa da volts 14.5, kuma matsakaicin bai wuce volts 14.9 ba. Bayan cire caja na tsawon awanni 24, yawanci yana kusa da volts 13 zuwa volts 13.5. Kimanin volts 12.8 zuwa 12.9 bayan mako guda. Takamaiman ƙimar ƙarfin lantarki na batura daban-daban ya bambanta.

Batirin lithium na yau da kullun shine 3.7v, ƙarfin lantarki shine 4.2v lokacin da aka cika caji, ƙarfin lantarki bayan haɗin jeri shine 7.4v, 11.1v, 14.8v kawai… cikakken ƙarfin lantarki mai dacewa (wato, ƙarfin fitarwa mara nauyi na caja) shine 8.4v, 12.6v, 16.8v… ba zai iya zama lambobi 12v ba, kamar yadda tazara tsakanin batirin ajiya na lead-acid shine 2v, cikakke shine 2.4v, daidai da haka kawai ƙarfin lantarki mai suna 6v, 12v, 24v… (Haka yake ƙarfin fitarwa na caja) bi da bi 7.2v, 14.4v, 28.8v… Ban san wane irin batirin lithium kake ba?
Fitowar caja gabaɗaya 5V ne, kuma volts 4.9 shi ma ba na yau da kullun ba ne. Idan kuna son amfani da wannan caja don cajin batirin kai tsaye, tabbas ba zai yi aiki ba, amma matuƙar an caji shi ta wayar hannu ko tashar jiragen ruwa, yana da da'irar sarrafawa a ciki. Za a iyakance shi a cikin kewayon da aka yarda da shi na batirin lithium, sai dai idan da'irar ta lalace, kada ku damu da wannan.
