<p>The invention relates to a square type enclosed storage battery of medium to large capacity, more particularly to a technology for realizing high volume capacity density or high output density, and is hence intended to present a square type enclosed storage battery of medium to large capacity of high reliability and small temperature rise, comprising a electrode plate group laminating plural layers of positive plates 8a and negative plates 8b through separators 8c, and a synthetic resin case 10 for accommodating the electrode plate group 8, in which a nickel-made terminal 2 has a pair of screws 2a as external output terminals of positive and negative electrodes, a pole portion 2b, a sealing groove 2c, and a current collector 2f, their central axes are designed to be nearly on a same line, plural current collectors 2f project from a flange 2d to the electrode plate group side, and the terminal 2 is fixed by a synthetic resin cover 1. <IMAGE></p> |
