The potential for reverse polarity damage has become more significant in recent years due to the proliferation of devices with rechargeable batteries. These batteries are often connected to charging circuits that can be sensitive to reverse polarity.
Reverse polarity can occur when the terminals and the cables are incorrectly connected. When polarity is reversed the current is going in the wrong direction. During this situation, if anyone touches the device, it can cause electrical shocks or it can damage the device. So,
Yes, a 12V battery can reverse polarity if it is connected incorrectly. This can happen when the positive and negative terminals are connected to the wrong terminals of the device being powered. If this occurs, the battery may be damaged and can even explode, causing a safety hazard.
It may discharge the battery with spark or permanently damage the battery. In other words, the reverse polarity battery connection, the DC supply would drag electrons from the negative terminal of the battery and push them at the positive terminal. This would gradually discharge the battery same like in case of a capacitor.
That same previously discharged battery would then be vulnerable to reverse charging, either by connecting the battery charger backwards, or by a charging system that reversed polarity (very rare, but still possible).
We know that a secondary battery (also known as an accumulator) is a device that converts the chemical energy into electrical energy and stores in it for later usage. The chemical reactions in secondary cells are reversible in case of proper battery polarity connection instead of reverse polarity.
