IUoU battery charging is a three-stage charging procedure for lead-acid batteries. A lead-acid battery''s nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge. Float voltage varies depending on battery type (flooded cells, gelled electrolyte, absorbed glass mat), and ranges from 1.8 V to 2.27 V. Equalization voltage, and charging voltage for sulfated c…
