How in earth to solder a wire to the 2032 battery? Which can only hold around 125 Celsius I believe..

I know there are those Battery holders in some Old PC's like these:

But.. I'm not sure how to cut them off and re-use them.
How did you guys do it, and how to do it/where to get the battery holder?
I would be very thankfully, as after this I can play on my CD-i for about 10 years again without problems.
