PURPOSE:To effect pressure measurement taking influences of a battery jar and partition walls thereon into consideration and thereby easily and properly determine pressure applied to an electrode plate group by measuring said pressure applied to the electrode plate group pushed into an electrode cell chamber as it is without taking them to the outside upon said pressure measurement. CONSTITUTION:Polypropylene partition walls 2, 2', 2'' are provided in a battery jar 1 to form six cell chambers, and a group of electrode plates 3, 3', 3'' are respectively housed therein excepting one chamber 4 among said cell chambers. Thereafter, a load transducer 6 having the same thickness as that t of a cell chamber 4 which does not yet house any electrode plate is housed in said cell chamber 4 while it is put on a pressure measuring iron plate 5 and brought into close contact with the partition walls. Then, a pressure measuring instrument 7 and a pressure gauge 8 both attached to the load transducer 6 measures pressure applied to the electrode plate group 3, 3', 3''. Provided that the pressure applied to the electrode plate group 3, 3', 3'' is less than prescribed pressure to be applied to the electrode plates, spacers 9 are inserted into the cell chamber 4. A number of the spacers 9 to be inserted is increased until the prescribed pressure is reached. |
