A process of manufacturing valve-regulated lead-acid batteries, comprising pasting lead alloy grids with a paste comprising lead oxide, sulphuric acid and water, thereby forming plates which when recently pasted are wet, characterised in that said process comprises the steps of: (a) applying at least one layer of a non-woven glass microfibre material to at least one face of at least one of said wet recently-pasted plates, and (b) wet calendering said plates having at least one layer of a non-woven glass microfibre material with rollers to obtain a final pre-determined plate thickness, whereby a reduction is obtained in the thickness of said layers of non-woven glass microfibre material of 20 to 40% with respect to its initial non-compressed value. Thereafter, and optionally, the process furthermore next comprises applying a compression step during at least one of the curing and drying processes of the plates, which gives rise to an additional reduction in the thickness of the mentioned layers of non-woven glass microfibre material of 10-15% with respect to its previous value. Lastly, likewise optionally, the process further comprises applying an additional compression step of the group of plates prior to its insertion into the battery container, giving rise to an additional reduction in the thickness of the said layers of non-woven glass fibre material, of 10-15% with respect to the previous value. |
