Did You Know That Batteries Can Flip Polarity?
Yep, this can happen if you have non-matched cells in series, or one dodgy one. The lower charge one discharges first and then the others in series push current through and reverse charge the dead one. Many products have a warning not to mix fresh and used cells for this reason. This has popped up quite a few times in my videos over the years.
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.

6 FAQs about [Can the battery be charged in reverse ]
Does a battery have a reverse polarity?
My battery has a reverse polarity but was never charged backwards, at least with a charger. My question specifically says right in the title OTHER THAN BY BEING CHARGED BACKWARDS. It is reversed, but at a pretty small voltage. The cells are in series, so it is possible if they become imbalanced for some to get reversed charged by the others.
Can You reverse charge a wet cell battery?
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 battery be recharged backwards?
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).
What happens if a battery is reversed?
The positive terminal of the cable is powered by +12V, while the negative terminal is powered by -12V. If the positives and negatives are reversed, the battery will attempt to compensate by converting the negative 12 volts to a positive charge, resulting in a massive burst of power and massive amounts of heat.
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.
