Hello,
of course these small plastic pieces don't protect the calc from getting corroded contacts.
Instead, these 'shields' were meant to provide better
phyical contact between the battery terminals of the calc
and the poles of the batteries themselves.
And they were constructed to aid the battery holder preventing
to loose batteries when transported outside the calc.
These nice plastic shields were produced for a while in
quantities and shipped with the HP-41, but obviously abandonned,
maybe because of cost reasons,
or because the metallic poles of these little plastic helpers have somewhat too sharp edges,
and you're likely to damage your calcs battery contacts mechanically from them over time.
