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.

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,
