Black & Decker 12V Univolt - Dewalt dw9050 Ni-Cd battery pack repair

[Kiriakos GR]

This is actually one presentation of pictures demonstrating internal battery pack formation of battery pack marketed as:
1) Black & Decker 12 V Univolt
2) Dewalt dw9050

Specific battery belongs to Black & Decker 12V Proline series of rechargeable drill.

The owner of this tool purchases it at the year 1992 and nowadays mid of 2018 he asked me If I can open it about examining the possibility of battery pack repair.

Specific battery pack assembly this is worst from all I have seen in my life, in the regard of opening it and reuse it.
Either way I did succeed at opening this battery box and now I feel proud of my self. 

Next step this is internal battery cells to be replaced and then I will reseal it in a way that reopening in the future this would be also possible.
