PURPOSE: To quickly recover the capability of a lead-acid battery having a function reduction and prolong the operating life by containing a surface active agent in an electrolyte, and using a perfluoroalkyl ethylene oxide addition product as the surface active agent. CONSTITUTION: A surface active agent is contained in the electrolyte of a lead- acid battery having a function reduction, and the boundary tension between the electrolyte and an electrode plate is reduced to 10-40-dyn/cm in particular by the infiltrating action of the surface active agent. When the surface active agent is used to reduce the boundary tension of the electrolyte, hydrogen bubbles are hardly stuck to the surface of an electrode, stuck bubbles are easily separated, the polarization by the hydrogen on the electrode is reduced, and a hydrogen trouble is reduced. When a perfluoroalkyl ethylene oxide addition product is used as the surface active agent, the capability of the lead-acid battery having a function reduction is quickly recovered, and the operating life can be sharply prolonged. |
