I don't know of any batteries that are designed to be soldered. You can use
some of the "miracle" fluxes to do it but most battery packs have
spot-welded leads on the bats. Hughes make a lot of the more commonly used
welders. Two welder contacts very close to each make the connection. Once
considered a DC cap type discharge to do it. Low voltage, "high" current
(just a few amps, if that much), very quickly discharged. Doesn't take
much.

Where can you buy rechargeable batteries such as Panasonic 1.2 Volt which
are designed to be soldered. I took apart my battery packs for my 18 volt
cordless drill and they have 15 NiCad batteries which say Panasonic 07-99.
They are wrapped in brown paper and made in Japan. Thanks
