Abstract: Monobloc batteries include compartments containing cells. Terminals extend into the compartments and are electrically connected with the cells via tabs. The tabs are folded to form bent stacks and include openings in partial registration with each other. The terminals extend through the openings and are secured to the tabs. The terminals are off-center relative to the compartments to preserve space for the bent stacks.
