FIELD: electrical engineering; lead battery manufacture.
SUBSTANCE: proposed lead battery has strengthened active material on its positive plate thereby enhancing its utilization efficiency at low internal resistance of battery. Novelty is that only positive plates hold in their voids gel-like sulfuric-acid electrolyte and remaining space of battery is filled with liquid sulfuric acid electrolyte.
EFFECT: enlarged service life of battery.
