i am fitting remote battery holders to all my pins best thing to do 
Agreed. I've fitted all games except Time Warp as that was with a mate, just got it back so I'll be fitting the remote this weekend.
I've used these -

If game needs a diode to stop charging (ie doing this to a game that had ni-cads, like an old Gottlieb board) better off with a four battery holder so you can install the diode neatly in the unused spot.
