I stumbled upon an old Thinkpad with an empty CMOS battery. Sadly it was shrinkwrapped, so I took the one naked CR2025 I still had and wrapped it in paper-ish packaging tape to prevent shortcircuits.
It’s working.

Very hot, very quickly. The trick is to have the solder hot enough to weld, but not have the battery or wire hot enough long enough to damage the internals of the battery. It really isn’t hard to do, but you do have to be fairly precise, and you’ve got more wiggle room than you’d think.
spot welding seems more appropriate when batteries are involved.
Basically, yeah.
