<P>PROBLEM TO BE SOLVED: To provide a charging method for suppressing a battery deterioration by agitating electrolytic solution to enhance the homogeneity (especially homogeneity regarding specific gravity) of the electrolytic solution, i.e. for prolonging the service life of a battery. <P>SOLUTION: A charging method of performing an intermittent constant current charge with an agitation of electrolytic solution caused by hydrogen gas generation, after a constant voltage/constant current charge for less than 12 hours at a voltage of 2.4 V to 2.5 V, and at a current value of 0.10 CA to 0.50 CA per one cell. Also, the intermittent constant current charge is performed at the maximum current value of 0.10 CA to 0.50 CA with respect to capacity of a battery to be charged, with one intermittent charging time of 1.0 to 5.0 minutes at a duty ratio of 60 to 70%, or till the time when the voltage becomes stable. <P>COPYRIGHT: (C)2013,JPO&INPIT |
