LEAD ACID BATTERY FORMATION TECHNIQUES

The 100 kg lead oxide are equivalent to 94.6 kg of lead. The reaction of the sulfuric acid with lead oxide leads to theo-retically 24.8 kg tribasic sulfate and after curing 79.2 kg lead oxide (neglecting the residual metallic lead) plus the expand-ers (1.4 kg). The average residual moisture after the drying is
