Robert,
Not long ago I had occasion to have a special battery made up by
BatteryPlus.
I watched the man use a fancy spot-welder. It had two small points made of
brass.
I asked him about it. The trick is to use the right amount of current to
make a solid spot-weld instantly without heating the battery. He showed me
a chart which told him what setting to use on different cases. He also
showed me different tips he uses.
BatteryPlus is a store where you can purchase batteries for almost anything.
If you need something super special, they will put one together for you on
the spot.

I suspect those leads are welded on before the battery is assembled.
I have soldered on wires to new batteries like this.
Scrape the surface of the battery first to allow the solder to stick and
don't get too hot while soldering
Heat is not a good thing for batteries
