Got a nicad battery pack to replace in a small loran set. It has 7
individual cells that are in series hookup by means of thin straps soldered
on tops and bottoms of pair, and wires coming off the pack to a small plug.

The replacement battery pack doesn't have the wires needed, so it looks like
I'm going to have to transfer the ones on the old/bad pack to the new/good
pack.

These wires were soldered onto the positive and negative battery contacts.
The question being how can I do that without damaging the batteries? My old
soldering stuff is too hot to use on these delicate things. So, what do I
go to for this task?


Your old soldering stuff isn't too hot, but if the tip isn't SHINY,
replace it. Scuff the battery with steel wool or scotchbrite or an
X-acto knife. Use some good rosin flux! (Required!) You should be able
to solder a small dollop of solder onto the battery very quickly. Then,
put another drop of flux on top of the solder, set the stripped and
tinned wire end into the flux drop, and reflow the solder.
