A battery terminal post seal manufacture wherein a battery terminal post (14) is sealed to a battery case wall portion (12) by a body of sealing material (17) fixedly sealed to the terminal post and movably sealed to the portion of the battery case defining the opening (13) through which the termina

A battery terminal post seal manufacture wherein a battery terminal post (14) is sealed to a battery case wall portion (12) by a body of sealing material (17) fixedly sealed to the terminal post and movably sealed to the portion of the battery case defining the opening (13) through which the terminal post extends. In one form, the sealing space (16) receiving the flowable sealing material is defined by inner and outer peripheral encircling ribs (18,19) on the terminal post. In another form, the outer closure (122) of the sealing space is defined by a cap (122) removably mounted to the terminal post end (123) by a threaded element (126). In another form, the terminal post is provided with a peripheral recess (227) within the battery case opening (213), with the post (214) having snug fit with the battery case in the opening so as to define the lowermost sealant dam. The invention comprehends forming the seal by introducing the sealant material in flowable form in situ with the structure defining the sealing space within the battery case opening. The invention comprehends determination of the completion of the filling operation by observation of the level of the sealing material in the seal space. In one form, observation is provided by a sight opening (21), in another form observation is provided by the filling of the sealing space prior to the mounting of the closure member to the terminal post, and in another form, a sight opening (221) is provided in the terminal post.
