ABSTRACT:
A perforated retainer is installed just under the top surface of the gelled electrolyte in a lead-acid storage battery to prevent the gel from crumbling and separating from the element plates when the battery is mounted horizontally. The size and density of the perforations are such that the retainer does not impede the initial introduction of the electrolyte solution. An the solution "gels", it cannot penetrate back through the retainer, but normal gas migration is not impeded by the retainer.
