It appears this calculator is an example of "planned obsolescence" by the manufacturer. Although the original battery can be replaced, the calculator does not seem to function properly afterwards!
This issue was discovered when attempting to run this calculator on a new battery after the original battery had discharged. The correct new battery style/type was used so that is not the issue.
An expensive calculator! Given that once its original battery has discharged, the calculator doesn't work properly on a new battery, so the calculator has to be thrown out!
Waste of money!
