This patent describes the method of assembling an electric storage battery including the principal steps of: providing a container having at least two adjacent cell compartments separated by an intercell partition having a notch therein; positioning a cell element in each compartment including an upstanding lug adapted for connection to an intercell connector; forming an intercell connector through the notch and between lugs of adjacent cell elements; positioning a mold tightly about the lugs, notch and surrounding partition; and injecting plastic into the mold so as to fill the notch, embed the intercell, encapsulate the lugs and bond to the partition surrounding the notch the improvement comprising: positioning a compressible elastic collar about each lug; positioning the element in the compartment such that one side of the collar abuts the partition beneath the notch; and tightly engaging the remaining sides of the collar with the mold while pressing the one side of the collar against the partition to completely seal the joints between the lug and the partition and the lug and the mold. This prevents the plastic from escaping the mold into the compartment.
