I give this information from taking batteries apart. They are all different. The 2 black wires would normally connect to the negative of the battery cells. The red would go to the positive of the cells. The white would go to the charger p.c.b which would be fitted. (Some batteries have not got these. They are normally in the charger) Initially connect the red and black wires and test whether the drill works. Then connect the white and see if it charges You can identify which is the positive by using a multimeter. Have a look at u-tube for various videos on battery repair. Hope that solves your dilemma.
