Hi Slash,
Ok, first off - my way is by far the best way, however you will need to be at least semi proficient at soldering, or at least have a steady hand.
Ok, turn the motherboard (mobo) over and look at the main track side of the board (the side without the battery on). You will notice that underneath the battery, at one end of it there are THREE solder holes. The other end has just one.
Now the battery you have on there (Barrel) has a one pin leg at the negative end, and a 2pin leg at the positive end. These two pins go into the outside two holes, leaving the third, middle one, unused.
Those three holes in alignment all do Exactly the same thing - take current away from the positive end of the battery. The other end is similar - just the one hole, and takes current from the negative end.
I Strongly suggest desoldering the battery completely then attaching your two wires into the single hole, and any of the three on the positive end (though the middle one will be by far the easiest as it already has solder present whereas this next phase might lose you the solder in the outside two holes).
To desolder: do NOT expect to get the battery out with just a few dabs of the iron, its a gradual process. Start with the single leg (we are still on the underside of the mobo here). Apply the irons heat to the joint and then gently pull the negative end of the battery from the other side. You should feel it give way a little (but hardly at all). Stop desoldering and let that cool.
You dont want to give too much heat to any join for any length of time as if you do you run the risk of damaging the board, but shortish contacts, just enough to melt the solder, is fine.
Move onto the double leg end of the battery. Again, to one of the legs apply the iron, just enough to be able to feel the battery give a little as you (gently) pull on it. Repeat on the last leg. Now go back and repeat the cycle. Every time you melt the solder, move the battery a little bit further out of the mobo and eventually it will come out completley. If you have a solder-sucker then this will be even quicker. Usually three or maybe four cycles of legs is enough to take it off totally.
Once that's done attach your two wires in place of the battery. You may need to add in a little bit of new solder to make the contacts. Make sure the wires are at least 5cm's long - that way when you solder the battery onto the other ends you wont run the risk of heating the mobo up at all via the wires.
Dont forget to get the +/- the right way around. On the mobo, underneath where the battery used to be (top side) will be a + and - notation in case you ever forget ;-)
If you'r at all in doubt then contact your nearest User Group and ask for help. If SEAL is anywhere near you then I'd be glad to offer my services if you or anyone else needs them. I've done this sort of thing many a time now ;-)
Hope that helps.
TTFN!
