Question about Texas Instruments TI-84 Plus Calculator
The life of the batteries depend on the use. If calculator is on and running programs 24 hours a day, the batteries will not last more that 2 or 3 days. If you use it the calculator for 2 hours a day, fresh batteries may last a semester.
But I believe you want to check the CURRENT state of the batteries. You can buy from an electronic store or a dollar store a device that tells you if a battery is still good or not.
With the TI Connect software you can check battery status. See the screen capture that follows. To obtain the displayed window you must click the button DeviceInfo with calculator connected to the computer and TI Connect running.
