Scientific Explanation: Over-Discharge: When a battery is excessively discharged, the voltage can drop to a point where the chemical composition inside the battery changes. This change can lead to the weaker cells in a battery pack reversing their polarity. Cell Imbalance: In a battery pack composed of multiple cells, if one cell …
Outside a battery, current flows from its positive terminal to its negative terminal. Inside the battery, to stop charge building up, the current must flow the rest of the way round, from the negative terminal to the positive terminal. This flow is driven by the chemical reactions in the battery. In an electrolysis cell the current flows ...
