Abstract
A battery cover and vent cap interface seal for electrical storage batteries is disposed between the vent opening in the battery cover and the vent cap to establish a fluid-fight seal. In a first embodiment an annular sealing member is provided in each vent opening in the battery cover. The sealing members extend slightly beyond the inner periphery of the vent opening in the cover and are compressed by the vent cap plugs as the vent cap is installed. In a second embodiment annular sealing members are provided around each plug on the vent cap. The sealing members extend slightly beyond the outer periphery of the plugs and are compressed as the vent cap is installed on the battery cover. The sealing members are made of a resilient material that deforms more easily than the materials used for the battery cover and vent cap.
