摘要： A multilayer deep cycle battery separator comprising at least two layers of an automotive-sized separator bonded or welded together. The automotive-sized separator layers include a backweb having a backweb thickness between 6 to 10 mils, an overall thickness of between 25 to 65 mils, and a rib base width of between 20 to 35 mils. The automotive-sized separator layers also have an extraction time of between 45 to 75 seconds, thereby providing an overall extraction time of less than a standard deep cycle battery separator.
