PROBLEM TO BE SOLVED: To accurately charge electrolyte without using a complicated charging device by stopping charging electrolyte when the weight of a storage battery charged up with the electrolyte separately by several times reaches a prescribed level after the storage battery contining no electrolyte with a cover set on a battery jar in which an electrode plate group is disposed. SOLUTION: A cover is set on a battery jar having therein an electrode plate group and other component elements, and then a storage battery containing no electrolyte is measured in its weight. The weight of dilute sulfuric acid electrolyte necessary for the battery is calculated by the conversion of the specific gravity from the capacity of electrolyte, and the calculated weight of electrolyte is charged separately by several times so that the preliminarily set battery weight may be obtained. An error in the weight of the battery at the time of final charging should be about±6.5 g. Accordingly, it is possible to allow the electrolyte whose amount gives an influence on the capacity of discharge to exist in the battery, with accuracy, thereby making characteristics of batteries even.
