[Elecraft] Elecraft] OT: soldering leads to coin cell batteries

[Fred Lozo]

Hello Captain John,
  I've attached wires to coin batteries by lightly grinding off a small patch of plating on the battery and then tinning that patch first with solder. Then I tin the wire and join the two together. Nothing to it.
Fair winds and calm seas,

Does anyone here have experience soldering leads to coin cell batteries?
My Compaq Armada M300 needs a new cmos battery.  the present one is a 2032 with 2 leads and a molex plug.

my
scheme is to put the needle point on my trusty WTCP, remove the leads
from the old battery, sand them and tin them and using the flux I used
for the smt project, quickly as in QUICKLY touch the point to the leads.

Why not?
