This work is devoted to the experimental study of performance characteristics shown by lead-acid starter batteries. The aim of the work was to study time patterns of self-discharge processes of batteries depending on modes, terms and conditions of operation, in particular, changes in their open circuit voltage, chemical composition and electrolyte density. Operating conditions of different climatic zones, which vary widely, were simulated in special control and test stations. It is shown that the increase in the content of impurities in electrolyte solution and, to a greater extent, its increased temperature leads to the increase in selfdischarge. Multi-day self-discharge time constant allows providing self-discharge compensation at the level of decline in units of ampere hours.
Key words: battery, control and test station, self-discharge, density, electrolyte, EMF, chemical composition, charge.
