The utility model relates to a battery field, purpose provide a lead acid battery baffle electrolyte separator. A lead acid battery baffle electrolyte separator, includes: the base is equipped with the upright seat of supporting inclined plane and main aspects and base upper end being connected, and the rocking arm group of the relative both sides of upright seat end is located to two symmetries,and a terminal surface and supporting inclined plane be parallel arrangement's stripper plate relatively just, the push -and -pull piece be connected with another terminal surface of stripper plate, rocking arm group comprises with an upright seat side articulated rocking arm respectively at least two parallel arrangement and one end, and the other end of rocking arm is articulated with the stripper plate respectively, the base upper end is equipped with upper end and the relative reservoir of supporting inclined plane lower extreme, the base side is equipped with the stop valve with the reservoir intercommunication. It is higher that the rate is extruded to the little and electrolyte of this lead acid battery baffle electrolyte separator intensity of labour, and the AGM baffle that needsis less and be difficult for impairedly.
