What type of battery is used in the TI-36X II Scientific calculator and how is it installed?
The TI-36X II Scientific calculator uses one CR-2025 lithium button cell battery. About replacing the button cell battery on a TI-36X II 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.
To replace the battery:
1) Remove the screw case, using a small Phillips® screwdriver.
2) Carefully separate front from back, starting from the bottom. Caution: Be careful not to damage any internal parts.
3) Remove battery, using a small Phillips screwdriver if necessary; replace the old battery with the new battery. Install battery according to polarity (+ and -) diagrams.
Caution: Avoid contact with other TI-36X II components while changing the battery.
If necessary, press ON and CLEAR simultaneously to reset. When released, memory and settings are cleared and MEM CLEARED is displayed.
Properly dispose of the used battery immediately. Please see the TI-36X II guidebook for additional information.
