PURPOSE:To enable intercell connection at low temperature while saving energy by a method, in which the central tip parts of both of each tappet or either of them of the positive-and-negative pole pillars made of a lead alloy for intercell connection are formed of the lead alloy having a low melting point or the intercell connection is performed by pole pillars applied with the powdered-or-pasted lead alloy having a low melting point. CONSTITUTION:A through hole 3 is formed on a partition 2 of a battery jar 1 made of sythetic resin. Next, the positive-and-negative pole pillars corresponding to the partitions 2 of a pole plate group 4 are inserted into the partition through holes 3 for making them to be contacted each other. Further, the electric resistance welding electrodes are connected with pressure for being conductively impressed. The resistance heating temperature at this time is set up at nearly 200 deg.C. The lead alloy 11 having a low melting point attached to the tappet 7 and the tappet 9 is melted for forming the fixing of the tappets 7 and 9 at about 200 deg.C. Accordingly, the resistance heating temperature exceeding about 300 deg.C as in the case of a lead-antimon alloy. The alloy having the low temperature melting point here to be used shall be the lead-tin alloy, in which 50% of tin is mixed. |
