The invention belongs to the field of storage battery design and manufacture, and specifically relates to a lead-acid storage battery with a vertical type storage battery horizontal connecting structure. On the basis of the vertical storage battery, an electrode wiring post terminal which is consistent with the vertical direction of a vertically placed battery pole plate is redesigned into the setup connection that the wiring post terminal is parallel to the upper horizontal edge of the vertically placed battery pole plate, so that the horizontal connection of the lateral exposure of the wiring post terminal of the vertical type storage battery is achieved, thus the advantages that the internal process and structure of the vertically placed storage battery are mature in technology and safeand reliable and so on accumulated in the hundred years of application and continuous improvement process are inherited; and besides, the production is simple, and can be achieved only through the improvement of the post terminal and the position change of a battery cover post terminal nest-shaped hole; and the original production implementation, the production process, most of tools, fixtures and moulds can continue to be used, the original production resources are fully used, and especially the production skills of original production staff are played continuously.
