The sealed cylindric Pb-acid battery cell has a tubular negative electrode inside of which a cylindric part of positive active material is located. A tubular separator is arranged between the electrodes. The electrolyte of sulphurous acid penetrates the positive, the negative electrode and the separator. The arrangement is characterised by that a positive grid, containing Pb is provided. A first part of the grid is in the proximity of the positive active material and a second part of the grid lies on a diametrical plane of the cylinder of active material. The cross-section of the positive grid may be S- or e-shaped. The Pb (free from Sb) in the positive grid may be a cast piece or an expanded metal piece.
