Electric accumulator battery, which comprises a receptacle (1) with cover, of a size which fits in the compartment traditionally reserved for this purpose in a motor vehicle. This receptacle is subdivided internally into a series of cells (2) that are distributed in two or more parallel rows between which are formed intermediate ventilation ducts (3), which are open to the outside through the bottom and the cover.

1. Electric accumulator lead-acid battery, which comprises a receptacle with a cover, of a general rectangular prismatic shape, of dimensions that adapt to an engine compartment in a motor vehicle, characterised in that said receptacle is internally subdivided into more than 6 cells, which are distributed into two or more parallel rows between which the said receptacle forms intermediate ventilation voids which penetrate to the outside through the bottom and cover and constitute ventilation ducts. 2. Battery according to claim 1, characterised in that the intervening cells are distributed in two rows between which is situated a ventilation void, which runs between a transversal wall of the receptacle and the last cell of the two rows, said rows being separated by an intermediate partition through which passes an electrical connection strap between plates. 3. Battery according to claim 1, characterised in that the cover of the receptacle forms on two of its opposite sides and underneath a top surface, cavities of a size which permits the fingers to be inserted. 4. Battery according to claim 1, characterised in that the ventilation voids are situated between every four central adjacent cells, permitting uniformity in the temperature of said cells. 5. Battery according to claim 4, characterised in that ventilation voids are delimited between every two consecutive outermost cells. 6. Battery according to any one of claims 1, 2 and 3, characterised in that positive and negative plates that constitute electrodes, are of a flat spongy type, in which all plates of a common polarity are contained in a separator to physically isolate them from plates of opposite polarity. 7. Battery according to any one of claims 1, 2, and 3, characterised in that a separator that isolates plates of one polarity from plates of an opposite polarity, is of a glass micro-fibre type and the cover has at least one gas-pressure safety valve, constituting a recombination type battery with electrolyte fixed in the glass micro-fibre separator. 8. Battery according to any one of claims 1, 2, and 3, characterised in that the cover comes with at least one gas-pressure safety valve and an electrolyte is fixed inside each cell by formation of a gel, thereby constituting a recombination type battery with fixed solid electrolyte. 9. Battery according to any one of claims 1, 3, 4, and 5, characterised in that positive and negative plates that constitute electrodes of each cell are wound to form a spiral and are separated by a glass micro-fibre envelope, thereby constituting a recombination type battery with electrolyte fixed in a glass micro-fibre separator, whose cover has at least one gas-pressure safety valve. 10. Battery according to claim 6, characterized in that a separator that isolates plates of one polarity from plates of an opposite polarity, is of the glass micro-fibre type and the cover has at least one gas-pressure safety valve, constituting a recombination type battery with electrolyte fixed in the glass micro-fibre separator. 11. Battery according to claim 6, characterized in that the cover has at least one gas-pressure safety valve and an electrolyte is fixed inside each cell by the formation of a gel, thereby constituting a recombination type battery with fixed solid electrolyte. 12. A battery according to claim 1 wherein said receptacle is internally subdivided into 18 cells.
