Abstract：
 This invention relates to a repairing technology of lead-acid storage batteries characterizing in including (mass percentage): Na2SO4 1-5, basic NaCO3, 4-8%, C4H2O6Na2 0.2-0.8%, Na2SiO3 1.5-2.5%, CH3COONa.3H2O o.2-0.8%, Al powder 0.01-0.025%, `lignin Na2SO3 0.005-0.15%, methyl-phenol 0.01-0.04% and deionized water, which fully utilizes rather active metal ions to act with lead ions in the sulfate to remove the sulfate and analyze it to sulfate radical ions and lead ions useful to the batteries and accelerate the reaction with current pulse.
