soldering possible? Review by df
now if welding does not work, will solder stick mayhemP

It's only possible to laser point weld it

you really cannot spot weld this Review by Artjom
I could not believe the previous review. So I tried it out. I have experience in spot welding. This one did not work. Negative on the cell is holding with 100Joule, no problem. But the positive on the cell just crumbles down on the contact points. Never seen a cell like this. (Posted on 16-05-21)
BEWARE! Not for spotwelding Review by the Battery Doctor
Capacity test at 500-2000ma shows 3300-3400mah. However these cells are not for spotwelding and does most likely not have an internal fuse system. The top cap is solid and most likelly only for wirebounding machines, Regular nickel will just not stick to it. BEWARE! (Posted on 23-04-21)
