Can a Battery Change Polarity?
What exactly causes a battery to reverse its polarity? Polarity reversal in batteries is typically caused by over-discharging, especially in rechargeable batteries like NiCd and NiMH. In battery packs, if one cell discharges faster than others, it can be ''pushed'' into reverse charge by the remaining cells, leading to polarity reversal.
