PROBLEM TO BE SOLVED: To suppress, without increasing the electric resistance and cost-up of a material, a dendrite short-circuiting prone to be generated in a separator in electrolytic solution injection and over-discharging because the space between electrode plates accompanied by a down-sizing of a battery is narrowed in a valve-control led lead battery. SOLUTION: This is the valve-control led lead battery in which boric acid exists inside the separator and in which the separator is used, and because the boric acid 2 remains solid in the separator in which a glass fiber 1 is the main body when an electrolytic solution in charging has a high specific gravity, this battery can show an effect as an inhibitor against the short-circuit by the dendrite especially in the electrolytic solution injection and in the over- discharge.
