    • Ensure that your calculator is a TI-30X IIS by looking in the top right corner of the front face.

    • Look at the rear face of the calculator and locate the four case screws. There are two at the top and two at the bottom.

    • Use a Philips 00 screwdriver to remove the four case screws on the rear face of the calculator.

    • Be sure to save the screws in a secure place as they are small and easy to lose. They will be needed later for reassembly.

    • With all four screws removed, use a flathead screwdriver or similar flat object to separate the front and rear casings.

    • There are six clips that keep the cases together. These areas will require extra force to separate, but use caution to not fracture the plastic pieces.

    TI should have indicated the 6 clips on the back or sides of the calculator. Thanks for showing!

    I have a TI-30X IIS but mine has 2 clips at the top about 1/3 of the way in at each side and the battery is attached to the backside (as someone commented below) with a wire attaching it to the front, so be careful separating the sides..

    Thanks for this tutorial!!!

    • With the rear case off, the battery is exposed and accessible.

    • Using a pointed tool, slide the battery out of its terminal towards the near edge.

    • Once the battery is protruding from the contacts, remove it with your fingers.

    This process varies as there are two versions I know of, one like the one in the picture, and one with the battery in the back cover.

    So that should help if you are scratching your head saying why they look different!

    Thank you bongo guy. Mine was on the back, which was connected to the front by a wire, so be careful separating the sides.
