 I expected at least some voltage, but it became clear that the battery was totally empty. When trying to charge it with my lab power supply at 7 volts, I expected at least some charging current, but there was none either. This was a clear indication that the battery must have been totally broken.

 The option to throw it away was not an option, since these battery cases are hard to find these days, even though it could be a rewarding and interesting 3D printing project. So I decided to bring it to new life again.

 I could not find out what the third connection on the battery pack is good for. I tried the pack, and it works fine, so I just left it unconnected.
 The final step is to seal everything. Considering what I wrote at the beginning: BP-84 cases are hard to get these days, so I won't seal it in a way that another battery service will not be possible. I chose black SIKAFLEX for this purpose.
