Zusammenfassung:	The invention relates to a method for producing lead acid batteries at the boiling point of the electrolyte, having improved cooling during production. The boiling point can be adjusted by applying a vacuum. At the boiling point, the latent heat causes a cooling effect, and the temperature is determined by the applied vacuum and kept constant. The vacuum is conventionally selected to be under 500 mbar (50 kPa) and, in particular, between 100 and 200 mbar (10 and 20 kPa). The invention relates to an efficient cooling method for all lead acid battery types, such as wet cell, AGM and gel batteries. The cooling effect is greater than that achieved by cooling in a water bath or by acid recirculation. The method permits the production time to be reduced to a few hours, in particular for AGM batteries.
