Seibu SP1 battery

[plasticfactory]

Does anyone happen to know what specific part I would need to install a battery holder in these boards? They all seem to have a little clip with a (now) dead battery already soldered into place. I'm sick of not being able to put these things on free play! Plus, the high score saves would be nice.

EDIT: Damn, 50 views and no replies. Am I barking up the wrong tree or did I go about this wrong?
EDIT2: Found my answer.
