batirin lithium:

Batirin lithium wani nau'in batura ne da ke amfani da ƙarfe na lithium ko alloy na lithium azaman abu mara kyau kuma yana amfani da maganin electrolyte mara ruwa.Ana iya raba batirin lithium kusan kashi biyu: baturan ƙarfe na lithium da baturan lithium-ion.A shekara ta 1912, Gilbert N.

Batirin gubar-acid:

Batirin gubar-acid (VRLA) baturi ne na ajiya wanda akasari na'urorin lantarki na da gubar da oxides ne, kuma wanda electrolyte shine maganin sulfuric acid.A cikin yanayin fitar da batirin gubar-acid, babban abin da ke tattare da ingantaccen lantarki shine gubar dioxide, kuma babban abin da ke haifar da mummunan electrode shine gubar;a cikin halin da ake cajin, manyan abubuwan da ke cikin ingantattun na'urori masu kyau da marasa kyau sune gubar sulfate.
