Victor,
saw the photos. Dīd not like the look. Didn't look like being done very 
professional. Made an investigation of Lion-batteries for a security company 
one year ago.Their imprints were larger and had a soft and regular coining 
of the stripe. Your battery stripe seems to have too sharp and deep marks, 
and they are all different, which may be because a varying process,. I guess 
on too much pressure and a too short pulse. Just guessing. How will the 
stripe look like if you pull off it?

Have a look at  the videos. In the end of these, you get a glimpse of how 
the battery welds should look like.

The base leave/foil for the battery metal is nickel.

Inge,

   I am not sure which method/process is being used on the notebook
battery spot weld.   IMHO, there must be some type of guideline for
acceptability.   Optically, one of the metal leaves/foil material
reflowed at the interface an left an open arch.   Somewhat difficult to
explain.   I will attempt to post a photo for all to see.

Victor,

Fellow TechNetters:

   Can someone share their experience with spot weld guideline as view
optical and with x-ray.

Victor,
