NOVELTY - A battery activator pellet comprises a timed-release acid dissoluble organic polymer (3) made from polyvinyl alcohol, polyacrylic ester, polyacrylic acid, lignin, silver, indium salt, or a germanium compound. A glass fiber (7) is embedded within the organic polymer. The timed-release acid dissoluble organic polymer pellet is assembled in an acid electrolyte of a lead-acid storage battery. The pellet comprises a core of the organic polymer coated with a layer of the erodible filler.    USE - For e.g. lead-acid batteries used for cars, trucks, buses, forklifts, or golf carts.    ADVANTAGE - The battery activator pellet recovers deteriorated lead-storage batteries and extends their useful lifetime.    DETAILED DESCRIPTION - A battery activator pellet comprises a timed-release acid dissoluble organic polymer encased within an outer casing that has a hole(s) (2) to permit a controlled rate of an acid electrolyte solution to diffuse into the casing to contact and controllably dissolve the organic polymer and adapted such that the dissolved organic polymer material so formed can be diffused from the casing. The diameter of the hole(s) is less than or equal to 3 mm (preferably less than or equal to 0.1 mm). The organic polymer is made from polyvinyl alcohol, polyacrylic ester, polyacrylic acid, lignin, silver, indium salt, or germanium compound. The casing is plastic, glass, or acid-resistant film. The organic polymer is a blend of a first acid dissoluble organic polymer with an additional acid dissoluble organic polymer having a dissolution rate different from the first acid dissoluble organic polymer. The organic polymer is blended with water. The organic polymer is a compressed powder or heat melted powders. A glass fiber is embedded within the organic polymer. The timed-release acid dissoluble organic polymer pellet is assembled in an acid electrolyte of a lead-acid storage battery. The pellet comprises a core of the organic polymer coated with a layer of the erodible filler.    An INDEPENDENT CLAIM is also included for extending the life of an acid-lead storage battery.
