Abstract: In a lead acid or the like storage battery having a case and a plurality of cells with each cell having positive and negative plates. A first cell connector strap connects negative plates of one cell to the positive plates of an adjacent cell successively and terminates in a positive terminal connector upon the interior of the case. A second cell connector strap connects the positive plates of one cell with the negative plates of an adjacent cell successively and terminates in a negative terminal connector upon the interior of the case which has an apertured closure base. A platform is mountable upon a vehicle or other support and includes a pair of projecting terminal connectors adapted to be received and projected up into said case for respective connection with the positive and negative terminal connectors respectively. Mounted upon the platform is a connector adapted for connection to a ground and to a powerline respectively.
