I have done a similar technique.. i pump a bit higher current/voltage in breifly and it kind of does something that causes the cell to become alive again. I have only done this so far on Nickel Metal hydride so far.. I see someone has stated that they have gotten this to work on a sealed lead acid?
I am wondering what is causing them to become alive again. I am guessing that there may be some energy blockage inside the cell... perhaps even the one or more of the internal connections have slightly shorted.. and that the sparking with a higher voltage may create enough of an internal arch to mend the connections (re-soldering) through a form of induced arch welding? thoughts?
My problem was I needed to reactivate a 12v drill battery similar to the 1 you used for your 'zapping'. I used the same principal as here with my car battery. Guess what - that works too. Brilliant! I was about to go buy a new drill as new batteries are almost as expensive
The battery is dead because a metal spike grows between the plates. The ZAP burns this spike off. Sometimes you need more power than he is using. I use a Gel Cell & thicker wires. You need a high amperage for a short duration. Dont keep it on too long or the batter will heat up & you will destroy it. I have been using this trick for 25+ years.
The cell will NOT have the capacity of a new cell & will eventually go bad again.
@Texmurphy51 I wonder if this is what they refer to as crystalization through age.. and how a machine "re-conditions" the battery by melting away or zapping it away through use of heat generated by current? or perhaps it is a kind of internal arc welding heat generated inside the battery that breaks down this "insulating" debri buildup material?
good video; though how long do they hold then; thereafter? similar life per charge and number of possible charges or only good for a very short durration?
I'm NO electronic wiz by any means and was a bit skeptical with this restoration technique. I tried it and it really works. I have discarded untold number of rechargeable batteries because they no longer worked or held a charge.
Vedry good.

@upcycle There is a spike of metal that grows between the plates and shorts out the battery.
Another trick to remove this spike is to drop the battery hard on the floor. This seems to shatter the spike.
I have had the best luck using a short burst of high current through the battery.
This is a temporary fix at best but gets them working again.

@Texmurphy51 I am thinking this might be like creating electrolisis.. which breaks down the bonds of the metal atoms?

@upcycle The explanation from the battery manufacture is ...
Little spikes of metal grow between the battery plates and short it out.
The physical jolt or high amperage burns them out.
Thus the battery is useful again.
No magic

This tip is amazing. I REALLY works.
