The invention discloses a lead-acid storage battery and an electric car using such a lead-acid storage battery, and aims at providing a lead-acid storage battery capable of effectively shortening a current path between bus bars and reducing internal resistance, heat value, and temperature and current collection property fluctuation among single batteries, and an electric car. The lead-acid storage battery comprises a plurality of single batteries arranged side by side, each single battery comprises a single battery jar and a polar group, the polar group is composed of a plurality of positive plates and a plurality of negative plates which are arranged alternatively in a manner of being separated by separators, positive lugs on the positive plates of the same polar group are connected through a positive bus bar, and negative lugs on the negative plates of the same polar group are connected through a negative bus bar; the positive bus bar and the negative bus bar of the single battery are directly connected with the negative bus bar and the positive bus bar in the single battery jar adjacent to the single battery through metal connectors, the single batteries are connected in series, and the positive bus bars, the negative bus bars and the metal connectors are located at the same height.
