where the plugs from the battery go to. (And yes you see where better don't touch due to high voltage for the nixies :-) )

On this photograph you can see the plugs but battery not included:

Good luck

Yes, it has a rechargeable battery inside (which is probably dead).

So, just to be sure: I need anadjustable DC power supply like this and connect it to the plugs inside.
How do I know which cable I have to connect to which plug (I have never done something like this before)?
The plug on the outside of the case has 3 contacts, but I only need to connect the black and the red cable in the inside, right?

The calculator has 3 Watts at 6-7.3 VDC so I need 0.41 - 0.5 Ampere, right?

Thank you for your help
