Reversing the polarity on a battery can happen only a couple of ways. If you have a wet cell battery are filling it for the first time, and are using an old style battery charger, non smart charger, and short the terminals while you are filling it, yes it is possible to hook up the charger backward and reverse charge it.
Can a negative battery be reversed?
You could technically charge it up, negatively, and continue to use it, but your plates are designed with the positive plates being lead dioxide, and the negative being composed of a sponge lead, which would now be reversed. Because the reversed battery is no longer formatted correctly, it will only work to a limited degree.
How do you reverse a battery?
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.
Will a lead-acid battery reverse charge?
With a lead-acid battery it will reverse charge, but you may compromise the battery life and efficiency. I know the two poles are different materials (lead anode and a lead-oxide cathode). So, the chemical process is going to be slightly different and you may also overheat the battery solution is charged too fast. Exploding H2SO4 is very bad stuff.
