[RE-wrenches] Cell Cracks

[Dave Tedeyan]

Ray,
I have seen this many times while servicing systems. I have not noticed it
cause any issues,
at least for modules that are 3-8 years old. On one site, I too did an IR
scan and even curve
traced modules showing this, and there was no difference compared to other
nearby modules
that did not show this cracking. The attached photo is what I have seen a
lot of. It is very similar
although not exactly the same as the pattern your photos show. (you may
need to zoom in to
see it).

Cheers,
Dave
