It's not my area of expertise, but here's one application guide that does
differentiate between tab attachment methods with regard to potential cell
damage recommending welding over soldering:

Hello Michael,
Thanks for the quick feedback. So, based on it seems my interpretation is
more conservative, but less (not more) right!
Just to make sure we are on the same page, the subject of my query is just
EMC emissions testing, not the radio tests that you mention (conducted

Dear EMC & Radio experts,
I have a couple of questions about FCC compliance testing of devices with
radio modules.
If a device has a built-in radio module, that is already FCC
tested/certified, how must this device be tested ? Here below two

Hi Kevin,
I am having trouble understanding your situation. Is it a cell or battery?
What do you mean by new product? Was it somehow approved with another product?
Welding tabs to a cell would have no impact on the cell approval and is the
normal way of making the connection.
Best Regards,
Since the battery might have been exposed to excessive temperature, I would
say that it does need to be tested. Also, if it was electrically welded, it
might have been exposed to stray currents and/or powerful magnetic fields,
both of which could cause damage.
Why weld? Consult the battery manufac
I think I know the answer but I was wondering if the battery specialists
among us could advise if a battery that has already been issued with a
certificate of compliance to IEC 62133 would require
retesting/recertification if the terminals of a new product it is used in
are welded to the cell?
