$begingroup$ To make matters worse, short-circuit heat build-up within a cell is often limited by the fact that rapid current drain will cause a battery''s internal resistance to increase, but if one has a series stack of batteries, the internal resistance will have to operate over the stack voltage, not over the battery''s own voltage. For example, if one has a stack of …
High Current or High Voltage that damages components?
When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.

Specifically, when cells are in series, the one(s) with the least current capacity (due to imbalances during manufacture, or uneven deterioration) will be reverse charged by the remaining cells as the last few coulombs are withdrawn. In this state, the battery as a whole still would have a small net charge, as opposed to reverse charge... but then, over time, all the …
Preventing Sulfation in Lead-Acid Batteries
It''s also worth noting that sulfation can occur due to extreme temperatures. High temperatures can cause the battery to lose water, leading to a buildup of lead sulfate crystals.
