electricme:

Great idea on the temperature comparison.  This could be done fairly easily I bet.  Then, at least we could quantify our results and compare the recovery time, if any, of the cells.

@ All:

I received news from the other topic I started that Hans is alive and well.  No other details are available at this time.  This is great news.

@ Bill
Thanks Bill, I was a little concerned abt Hans.
I will be away for abt 4 days, my grandson is visiting.
Hoo roo
Jim

This is one.

I  just thought  I  would let you  know that I am changing names .

It  seems  that   most people  capatalise he  first  letter  of a name

In  my  case  that puts me  using the exact  same name as  another person here .

About   parts of your   batterys  heating  up .

Did  you know that   in the big induction  furnaces  that  they  use for  melting iron    there are only  2  windings ?
The primary  fills  a good share of the  furnace ...........the iron they are melting  is the secondary .


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I am  glad to hear that Hans is   OK .


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I   hope to  have  more to post   soon .

I am  out of here now .

Next stop ...... Lowe's ......in search  of copper and  stuff

No, I did not know that!! wow.

Because of that information the stuff folks say about eddy currents makes a lot more sense.
ALSO, I had an idea the other day to use not an iron stake for the core piece, but an iron pipe. I was thinking about letting the shape do more of a tpu type action. But, now I get what I was thinking that for. If the core piece can let megacharge through and not melt because it is a hole with earth in it...

and the induction will be much better on a bigger circumference...

and you say it is the secondary that heats up and becomes the iron in the furnace?   That means they are using iron for the secondary not copper...

wow

Thank you gary this is great information.

jeanna

also,I like your new name - very appropriate.

I  am  not  sure that  you  are  gettinng the right  picture here .

with the furnace  they  don't use an iron  secondary ...........the iron that they  plan to melt IS the secondary.

It works kind of  like it is one   big single  wrap.

Or in your  case .........  it works  like a spike  in the middle of a  coil   

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

yes  I am  sure that eddy currents play a big role in   creating the heat
