Under float-charging conditions, the voltages of all cells in a pack tend to be the same. Then, at a certain moment, the ISC is triggered. 6 Although the overall voltage of the pack will not change under constant-voltage float-charging scenarios, the battery with ISC will exhibit a continuous voltage drop, while the voltages of the remaining normal …
