Formation of battery plates can be conducted via two technological schemes: (a) Tank formation. 50–200 cured positive and negative plates are arranged in a tank with H2SO4 solution of 1.06 relative density. After soaking for 1–2hours, formation proper starts. (b) Container (jar) formation. Cured positive and negative plates, with separators between them, are assembled into “plate groups” which are then placed in battery containers. H2SO4 solution of 1.15–1.23 rel. dens. is used. Formation starts after 1–2hours of soaking.
