LEAD ACID BATTERY AND METHOD OF STORING IT

摘要

A lead acid battery comprising: a positive plate; a negative plate having higher capacity than said positive plate; a separator interposed between said plates; and an electrolyte, said plates and said separator being impregnated with said electrolyte, the amount of said electrolyte being limited so that a free electrolyte is not substantially present therein, the theoretical capacity of said positive plate being more than 2.5 times as much as the theoretical capacity of said electrolyte, and thus having an excellent discharge storage property; and a method of storing the retainer type lead acid batteries including above battery to improve the discharge storage property comprising permitting said battery to stand under such a condition that a load is connected between said positive and negative plates when said battery is allowed to stand after the discharge has been finished.
