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.
So if you connect the battery backwards, it's essentially a short circuit. Why would it be connected that way? I thought diodes used as protection would be connected to stop the flow of electricity in a reversed polarity incident I think that you are correct. Reverse polarity produces great currents because of breakdown of semiconductors.
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.
To reverse the action as prior, fully discharge the (reversed charged) battery and connect it to the right terminals (i.e. negative to the negative and positive to the positive terminals of charger and battery respectively). Again, wear the rubber gloves and glasses and other safety measures for proper protection while playing with batteries.
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.
Not at all. In addition, a fuse or a generic diode (Voltage drop up to 0.7V across the diode will occur) can be installed on the positive wire for one direction power supply which acts a reverse current protection.
