<p>The present invention relates to a method for restoring a battery. The method for restoring a battery comprises an outer appearance check step; a measuring step of measuring the possibility of restoring the battery by measuring the voltage of the battery with a measuring instrument; a punching step of forming a punching hole by punching some of the main body of the restorable battery; an ejection step of ejecting the electrolyte and sludge from the battery punched at the punching step; a purification step of purifying the electrolyte and sludge ejected at the ejection step with a filter; a specific gravity adjusting step of measuring the specific gravity of the electrolyte purified at the purification step and adjusting to a specific gravity appropriate to the corresponding battery; an injection step of injecting the electrolyte having the specific gravity adjusted at the specific gravity adjusting step through the punching hole; a sealing step of sealing the punching hole after the injection step; and a restoration step of connecting the battery to a restoration device after the sealing step, and removing lead sulfate formed in the inner electrode plate. According to the method, all the sludge formed in the electrode plate can be removed by the punching hole formed in each cell.</p> |
