PROBLEM TO BE SOLVED: To surpress deterioration of an electrode in an early stage caused by unbalanced burden on the electrode plate arising from vibration of a group of electrodes, by solidifying with alkali silicate a lower part of a group of electrodes for sealed lead storage battery in a battery jar and by arranging the group of electrodes at a predetermined place so that they do not move. SOLUTION: A lower part of a group of electrode plates is solidified with sodium silicate and the like under a condition in which the group of electrode plates consisting of a positive electrode plate 1, a negative electrode plate 2 and a separator 3 is contained in a battery jar 4. For example, electrolyte mixed with sodium silicate is injected in each cell, and after the group of electrode plates is inserted in the battery jar gelatin of the electrolyte is made by leaving it as it is or drying it so that the group of electrode plates are solidified. The sodium silicate to use is preferably composed of 20-21weight% of Na2 O, not more than 0.95% of SiO2 and 79-80% of H2 O. The lower part of the group of electrode plates is impregnated in aqueous solution mixed with sodium silicate and dilute sulfonic acid.
