Texas Instruments TI Rechargeable Battery with Pigtail Wire
- Computer through USB
*To determine if this is the correct battery for your unit, remove the back cover of your calculator and remove existing battery.
- If the existing battery has a pigtail wire that is plugged into the back of the calculator, this the correct battery.
- If the battery does not have a wire, you will want the TI-Rechargeable Battery without wire.
Will not work with the original Nspire, Nspire CAS, or any other calculators. Please contact us if you have any questions.
