Voo Doo Witchcraft and Alchemy re batteries - Woodworking Talk

Got some "dead" batteries? I had some that were dead for more than 5 yrs, just sitting there waiting for the grim recycling man come and bury them. Then I saw this article: http://www.jalopyjournal.com/forum/s...ight=batteries
So I thought I would try out the "zapping" technique. Try this at home, not at work, and wear your safety glasses even though nothing bad happened.

These batteries started at 0 volts, deadrn****, and were revived to 19.2 volts , last photo not shown after charging for 1 hr.

BTW the date on the battery was 02/96 more than 13 yrs old.
The set up:

People who shop at Wally World usually have the same exact tools.

Woody that's a trick worth trying I have a bunch of dead ones. Some of them are not very old. One of them is a 28V LiIon that went T.U. right smart after buying the blasted thing.

I haven't read the article yet so don't know if they mention if it works on lithium ions but I also have plenty Ni Cads on which to use the VooDoo. What will be of interest to em os how long they'll hold a charge now.

Thanks for the article.

Negative. Harbor Freight. Where have you been?

TT, LiIon batteries have different charge levels and charge differently than NiCd. It may work, but I'd suspect you may also need to do a little jimmying with the process to make it work. As for how much life after the "raising of the dead", it's all "extra" at that point anyway, isn't it?

TT you said"...One of them is a 28V LiIon that went T.U. right smart after buying the blasted thing.
T.U. means Toes Up, as in road kill? Totally Useless? Wait, I'll look on the acronism chart!

woodnthings... No, TU means Tango Uniform! Everyone knows that

Yeah what Frank said.

Thanks for bailing me out Frank I was trying to figure out how to answer that. I didn't even realize I typed it. Military flashback I guess.

No problem TT. Anything to help a brother out in his time of need

For any who don't know the etymology of TU, it's a good one... at least as I've always heard it... it basically it comes from the engines on a plane being above the wing instead of below (IE plane upside down) and that being a bad thing like the plane crashed wrong side up or somehow got upside down during flight. From the right angle, that looks like a [lady on her back] shall we say... thus T**s Up. Have fun with it...
