This paper is an investigation of the processes during curing of 3PbO {center dot} PbSO{sub 4} {center dot} H{sub 2}O and 4PbO {center dot} PbSO{sub 4} (with Pb{sub 3}O{sub 4}) pastes at 93{degrees}C and water vapor inlet. It was established that 3PbO {center dot} PbSO{sub 4} {center dot} H{sub 2}O is transformed into 4PbO {center dot} PbSO{sub 4} large crystals which are very slowly oxidized to PbO{sub 2}. That is why such plates have low initial capacity. Curing of 4PbO {center dot} PbSO{sub 4} pastes under these conditions proceeds very quickly (8--21h). Batteries manufactured with such plates have initial capacity equal to the rated one and cycle life considerably longer than that of batteries produced from 3PbO {center dot} PbSO{sub 4} {center dot} H{sub 2}O pastes.
