About replacing the cell battery on a TI-36X Pro Scientific calculator:
For safety purposes and to prevent ingestion, the button-cell batteries in school- and student-owned calculators without battery doors are not designed to be replaced. It is possible to replace the battery by removing the back case of the calculator, but opening the back of the calculator voids the one-year, limited warranty. This must be done carefully, as we cannot be held responsible for any damage caused when you attempt to replace the battery. If your calculator is already out of warranty, you might choose to remove the back case to replace the battery.

• Remove the slide case and turn the calculator face down.

• With a small screwdriver, remove the screws from the back of the case.
• From the bottom, carefully separate the front from the back. Be careful not to damage any of the internal parts.
• With a small screwdriver (if required), remove the battery.
• To replace the battery, check the polarity (+ and -) and slide in a new CR2032 lithium battery. Press firmly to snap the new battery into place.

Please Note: When replacing the battery, avoid any contact with the other components of the calculator.
