The first-cycle discharge capacity of tubular positive plates was determined as a function of formation conditions. "Infinite acid volumes" were used and formation conditions were more extreme (up to 152 h, 70 'C, s.g. 1.320 and paste densities from 3.2 to 5.5 g cme3) than those examined in a previo

## Almtrmt-The optimum conditions of formation for tubular lead/acid battery were studied by experimental design method. Electrode capacity was found to be maximum at a H,SO, concentration of 1.06 sp. gr., a charge amount of 150% theoretical capacity, a charge time of 36 h at a current density of
The effects, during formation, of current density, charge capacity, and concentration and temperature of HzS04 electrolyte on the capacity of tubular electrodes in lead/acid batteries have been studied. Electrode capacity was found to be maximum at a HzS04 concentration of 1.05 sp. gr., a charge amo
Tetrabasic lead sulphate (4BS) is only formed in battery pastes that see temperatures in excess of 70 "C. Although it is difficult to oxidise anodically, when converted to PbOz it forms the alpha-polymorph which gives the positive plate a long cycle life. This statement is a summary of what appear t
