"I think there was some kind of metal clip at the right hand side of the battery compartment, which now is missing. Maybe this gives the additional millimeter of space that's required for the two batteries. On the other hand you may also consider special flat top cells. These are slightly shorter than their regular counterparts."

In fact, the calculator came with a metal bracket which included the connection for the batteries opposite to the contacts, negating the requirement for the foil. There was no connection physically attached to the calculator opposite the contacts as the battery clip contained it.

The bracket made of metal increased the length of the battery and with new alkalines causes stress on the battery tabs. The foil works perfectly and your suggestion of the flat tops cells, if available is perfect.
