Default How to unseal cells on a NOS Y55 Delco Battery

I recently acquired a NOS Y55 Delco Battery from early 70's. It has never been used. The top of the cells have a Wax material, that I thought was sealing the cells. But I removed the wax from one cell, and under that the top of the cell is still sealed off with the Bakelite material. I'm puzzled. How are you supposed to open the cells to acid ? Do you punch in the material ? It will drop into the battery which does not seem right.

Also I need a set of Yellow push in Caps (5 regular, one Delco Eye) as it did not come with the caps. You would think for the amount I paid for it, it would come with caps.
