The first step of removing single cells from a battery was to drill holes into the lid above Cells 2, 4, and 6. The acid density of Cells 2, 4, and 6 was measured, each at top, middle, and low levels and acid samples were then taken for future analysis, shown in Table 2.The acid from Cells 2, 4, and 6 was carefully and stepwise drained.

Learn MoreCapacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity. While portable batteries can be cycled relatively quickly, a full cycle on large lead acid batteries is not practical for capacity measurement.

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…
