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. <IMAGE> <IMAGE>
1. Electric accumulator battery, which comprises a receptacle with cover, of a general rectangular prismatic shape, of dimensions that adapt to the traditional compartment intended for this purpose in a motor vehicle, characterised in that said receptacle is internally subdivided into more than 6 cells and preferably 18 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 one of the transversal walls of the receptacle and the last cell of the two rows, said rows being separated by an intermediate partition through which passes the 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 the 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 mentioned are situated between every four central adjacent elements or cells, permitting uniformity in the temperature of said cells. 5. Battery according to claim 4, characterised in that it includes also ventilation voids delimited between every two consecutive outermost cells or elements. 6. Battery according to claims 1, 2 and 3, characterised in that the positive and negative plates that constitute the electrodes, are of the flat spongy type, in which all plates of the same polarity are contained in a separator to physically isolate them from the plates of opposite polarity. 7. Battery according to claims 1, 2, 3 and 6, characterised in that the separator that isolates the plates of one polarity from the plates of the other polarity, is of the glass micro-fibre type and in that the cover comes with at least one gas-pressure safety valve, constituting a battery of the recombination type with electrolyte fixed in the glass micro-fibre separator. 8. Battery according to claims 1, 2, 3 and 6, characterised in that the cover comes with at least one gas-pressure safety valve and in that the electrolyte is fixed inside each element by the formation of a gel, thereby constituting a battery of the recombination type with fixed solid electrolyte. 9. Battery according to claims 1, 3, 4 and 5, characterised in that the positive and negative plates that constitute the electrodes of each cell or element are wound to form a spiral and are separated by a glass micro-fibre envelope, thereby constituting a battery of the recombination type with electrolyte fixed in the glass micro-fibre separator, whose cover has been equipped with at least one gas-pressure safety valve.
