METHOD FOR DETERMINING FOULING OF LEAD BATTERY ELECTROLYTE Russian patent published in 1999 - IPC

FIELD: storage battery maintenance. SUBSTANCE: method depends on determining increase in rate of battery self-discharge in case of electrolyte fouling. Self-discharge of storage battery is measured at 20 C and electrolyte fouling is estimated by ratio of battery self- discharge at 20 C expressed by in-service increment of electrolyte specific gravity to its originally recorded value in the beginning of service or to that given in battery specifications but also reduced to 20 C and expressed by increment of electrolyte specific gravity. EFFECT: facilitated procedure. 4 tbl
