A lead-acid battery includes a case having an apertured cover with the aperture being for passage of a terminal post therethrough for electrically connecting electrodes within the battery case to apparatus outside the battery, with the terminal post extending through the aperture. A rubber layer, devoid of rubber fillers and plasticizers, circumferentially surrounds the post at the aperture. A rubber-bonding epoxy polymer is between the rubber layer and the aperture through the case. A method of securely sealing a battery post within an aperture passing through a lead-acid battery case includes the steps of applying a rubber undercoat which is devoid of fillers and plasticizers annularly about the battery post portion which is closest to the aperture when the post is secured with the aperture, positioning the post within and annularly spaced from the aperture with the annular undercoat proximate to the aperture and filling space within the aperture between the annular undercoat and the battery case with a rubber bonding epoxy material thereby bonding to the annular undercoat and to the battery case.
