Battery "resurrection"?

[bmwpower]

Has anyone tried this? Any idea how they are doing the resurrection?

The ad definitely worked as designed (got my attention)

He is selling you the information of how to resurrect the batteries, not any hardware or tool to do this. Is his "intellectual" property worth $12.95 to you is the real question. Once you purchase the information, you are free to do with it what you want, so if it works, then you can blab that to anyone that you care to. If it doesn't work, then you are out $12.95 and can bad mouth his non "intellectual" property as being nothing more than snake oyl.
I already know what he is going to be telling you. You need to "hit" the battery with a high voltage charge to break up charge pack in the battery. I have heard of this many times before, but I have never tried it. I have heard that the battery can explode and you could get hurt, but I don't know if there is any truth to that claim.
Here is a link that explains how to do it for free.......... Here is a link that tells you how to build the zapper.

The plates in batteries these days are built so thin that once a battery fails, its game over......You notice that same cranking amp batteries are smaller these days than in the past.......thinner plates.................That is why, one day its good, the next, the car won't start.

Also, be careful....Batteries can and do explode...................


edit........OH...Cordless drill batteries.........never mind, but probably the same may be said about them.......................

Still leaving my rant on car batteries..................a new battery every 3 years is ridiculous.........

The idea with the voltage is akin to the de-sulfaters, they use high frequency AC to cause the sulfur crystals (that have coated the batteries plates and prevented the battery from flowing current) to separate from the plates and go back into the battery fluid. Don't know what this guys technique is, but true de-sulfaters do work, as we discussed a few weeks ago.

I believe with a NiCad that whiskers of metal perforate the insulation later and make internal shorts. Giving it a short ZAP is designed to **** those shorts.

There are some battery rejuv circuits that work other ways, but I don't that much about them. Best is to buy fresh new cells and replace the old ones. Maha I think makes a generic one that recharges all cells and hooks up with clips.

Well, either Rob the Slob has moved from Connecticut to Califooey and changed his product line from sandblasters for the insane to battery rejuvinators, or he has a cousin on the west coast.

Then again, this clown could be the copy writer for Easton compressors given the amount of **** he spews saying nothing.

Nicads that have gone deep discharge, reverse polarity or corroded cannot be recussitated. Motarola developed an excellent machine for their shops, $14,000- to rejuvinate portable batterys, and it only succeeds about 25% of the time.

Now if you have money laying around you don't know what to do with, send it to me and I'll mail you the secret formula to make permanent antifreeze at home.

Hay Junkman, I'm a new member. Tried to go the the zapper link but my browser couldn't find it, to you have an address I really want to see this "zapper". Thanks

I have got some of my old dewalt 18V batteries back from the dead. A friend told me to try this on an old dewalt battery that wont accept a charge....(if it isnt working anymore, you got nothing to lose).

He told me to take the dewalt battery & a set of jumper cables....hook the cables up to a charged 12v auto battery (preferably not one installed in your car). take the +&- leads and touch the leads on the dewalt battery for a second or so.
I did it, stuck the 18v battery back on its charger and it worked....the battery accept a charge again. i have only tried this with 2 of my dewalt batteries that werent working anymore and I was just going to recycle them. That was a year ago and the batteries are still going strong!

I figured I would give it a try, nothing to lose. I would never try this with a lipo or li-ion battery....i could only see bad stuff happen with that.

Hmmmm...I have 18v Ryobi batteries...nothing wrong with them yet, but when they go bad I'll have to try this.

It was a good site when I posted it, but as things often happen on the internet, sites go dark and never come back. Try a Google search to see what you might find.

Okay, I have 2 18v Dewalt batteries that won't hold a charge, one given to me by a neighbor and the other dug out of the recycling bin at Lowe's. Does it matter which lead on the 18v dewalt battery I touch with the positive or negative leads from the car battery? If it does, which is positive and which is negative on the 18v battery?

I was going to take these to Batteries Plus to have them rebuilt, but this could save me $100. or it could

Yes, the pos/neg matters. meter the contacts to see which is which.

Here are a couple ZIPs of PDFs that show the process. They're from some seller on ebay that someone else sent me a while back.

I've used them to resurrect a couple DeWalt 14.4V battery packs. They were dead, wouldn't accept a charge and afterwards I couldn't hold the chuck. They have maybe 80% capacity compared to new packs. Enjoy....

goto www.archive.org and punch in the url and see if it's archived - many are...

also, if you're using Firefox, there's an extension to search the archive sites when you gte a dead link. Forget the exact name but a search on "resurrection" should find it; if not, something liek "dead site finder" or the like should get it.

I have a Vector 1095A that I have used to bring a couple of batteries back from the dead using the de-sulfide feature. Most don't respond, but at least 1 Optima and an Odyssey have been restored to full use after dying and failing to hold a charge.

For the $35 I paid it's worth it just for the portability and charging, the reconditioning cycle is icing on the cake.

Battery "resurrection"? NI-Cad Zapper Links

All, Thanks for the info on getting my ni-cads back! Junkman left good info and a link that somehow got old and I wanted let you know it's still there, but modified:
http://www.atv-projects.com. On the left is the "NiCad Zapper" : http://www.atv-projects.com/NiCad_Zapper.html. They must have re-organized.
Also found this link, but it's best message is the warning:

Cheers!
