Durable Laptop Batteries
Zapping Batteries
How to ‘Zap’ rechargeable batteries that are dead or will no longer charge. Be careful when doing this and be sure to protect yourself from the batteries in the event they rupture or explode. The video does not show it, but when I normally do this, I place the battery under a plastic container with a slot to touch the negative lead.

See some of my replies? below, and some of the other comments. Most of the comments from others are accurate, thus far.
Excellent input! You are very correct. I’ve been doing it for quite some time to, but after conversation with a buddy, I decided to make a video. I like? sharing information.
I’m not familiar with the term “crystalization through age” but the term sounds like it could be appropriate.
It is not “insulating” debris that is the problem, it is actually conductive debris (or whiskers of? metal) that pose the problem because they grow between the plates inside the battery and essentially short it out.
The high current (as opposed to high? voltage) is the trick to burning out the whiskers that form on the surfaces inside the battery.
Do keep in mind that the voltage of your zapping battery must be higher than the voltage of the zapped battery (due to laws of electrical charge and flow).
You’ll find that you MAY be able to acquire some extended life,? but not necessarily a permanent restoration to its original capacity. See my reply to the comment below.
Keep in mind, they will eventually wear out, but this technique can provide a little more life to the batteries. It is not a panacea to battery deterioration, just a little health care to extend their life.
I have some batteries for my cordless? tool set that are over 10 years old, and have been used QUITE extensively.
Electrolysis is? applying voltage and current to a fluid to separate the molecules into atoms. Such as can be done with water, to create hydrogen and oxygen gases.
Exactly!?
If I were to wipe the battery acid off with a slightly damp rag, will I get zapped, or short it out?
If this thing is savable, should I brush a little of that battery? post grease on the ends after zapping and reconnecting the cells? (that is, if I even have to disconnect them in the first place?)
I forget if I charged this? today or not. Should the battery be fully drained before doing this , or should it be as charged up as it is able to get before doing this?
I opened the case and exposed the cells.
On? the top I see perhaps 4-5 (?) % coverage of light battery acid on most of the cells. Maybe it’s actually on all of them. On the bottom side there is maybe 1/4 th as much.
I wonder if that means there is no hope?
I forgot if it took a long time to charge or not, but it sure didn’t hold a charge for more than a few minutes.
Do I have to separate all the cells before checking them?
And Your video is very good. Thanks much
it? works! I tried it on some dead batteries and they are working and charging again. Simple and FREE!!
thanks,i will? try this
Vedry? good.
I am? thinking this might be like creating electrolisis.. which breaks down the bonds of the metal atoms?
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 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?
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
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.
This tip is amazing. I REALLY works.
