<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a sealed battery which enables the increase in the production efficiency of a sealed battery.SOLUTION: A method for manufacturing a sealed battery comprises: the primary injection step (Step S2) of injecting an electrolyte into each battery having a liquid-injection spout, which is a workpiece in process, through the liquid-injection spout; the step (Step S6) of sealing the liquid-injection spout after the primary injection step; and the step (Step S7) of picking out, from the battery workpieces in process, an acceptable one on the basis of an exposure time and a dew point temperature in an environment between the completion of the primary injection step and the sealing step exclusive, provided that the exposure time is a shorter time of a length of time between the completion of the primary injection step and the sealing step exclusive, and a length of time which has elapsed after the completion of the primary injection step.</p> |
