[Esterson/Pinsky]

Clean off the nickle plating with some sandpaper or a Dremel, tin it with a
hot iron quickly, and then use solder wick for the leads.

both the CR2016 and the CR2032 with good results. As I recall, there may be
a thickness problem with the CR2032.  I buy them with spot welded leads for
under $ 2 from DigiKey in the States. They have a great variety of 3 volt
lithium batteries. Some have plastic insulation on the edges which is a
plus. As I recall the plain CR2016 goes for about 38 cents. If you clean
the nickel surfaces and are fast with a small soldering iron, you can
solder your own leads on them.
