It can be seen from FIG. 2 that the battery of the present invention has a significantly improved cycle life as compared with the conventional battery. The reason why the cycle life is greatly improved in the battery of the present invention is that the electrode plate group is installed so that gravity is applied perpendicularly to the electrode plate surface. Therefore, the electrode plate group is installed so that gravity is applied in parallel. It is presumed that this is because the uneven distribution of the electrolyte solution and the uneven distribution of the solution concentration are greatly improved as compared with the case of the conventional battery. This means that the battery of the present invention is more likely to prevent downward migration of zincate ions caused by discharging the negative electrode plate 4 in the battery of the present invention, and the resulting change in the shape of the electrode plate is more likely to occur. It is estimated that the number will decrease.
