Summary:PURPOSE:To increase the charge acceptability of a battery allowed to stand after overdischarge by containing a perfluoroalkylamine oxide surface active agent represented by CnF2n+1CONH(CH2)3N<+>(CH3)3I<->. CONSTITUTION:A perfluoroalkylamine oxide surface active agent represented by CnF2n+1CONH(CH2)3N<+>(CH3)3I<-> is contained in a battery. Its content is 1X10<-4>-1X10<-2>wt%. Surface tension between lead sulfate and an electrolyte is reduced and the electrolyte penetrates into between crystals of lead sulfate having bad wettability to decrease charging current density. The charge acceptability of the battery allowed to stand after overdischarge is increased.
