  "textContent": "A lead acid battery can be obtained which exhibits excellent life properties while keeping the level of self-discharging and electrolyte loss equal to that of those comprising a Pb-Ca alloy collector. In other words, the present invention lies in a positive collector for lead acid battery comprising a substrate and a surface layer made of an alloy composition different from that of the substrate formed on at least a part of the surface of the substrate, characterized in that the substrate is a Sb-free lead alloy or lead and said surface layer is a lead alloy layer comprising one or more metals selected from the group consisting of alkaline metals and alkaline earth metals.",
