a far better approach for a collectable calculator would be to fashion a holder for two AAA sized cells. after all, even a pair of modern rechargeable AAA cells is likely to run one of these calculators for many hours of use.

a sleeve to encase AAA cells so they could be charged in an AA battery charger used to be available at Radio Shack. If these are still findable they might be, or be easily modifiable to, the shorter size - and offer some small protection against leakage too.

Me though, I'm lazy. I just leave the contacts broken and slip in alkalines with some aluminum foil at the bridge.
