What battery do I use for my rechargeable Texas Instruments Graphing Calculator? - Underwood Distributing Co.

The need for rechargeable batteries

Texas Instruments' Graphing Calculators have evolved over the years to be rechargeable and have a backlit screen. With these feature improvements, regular AAA batteries were no longer going to cut it. TI switched to using rechargeable lithium-ion batteries.

The Two Types

There are two types Texas Instruments Rechargeable Graphing Calculator Batteries.

One with a wire (or pigtail) and one without the wire (or pigtail).

Texas Instruments Rechargeable Graphing Calculator Battery for Ti-84 Plus CE and Ti-Nspire CX

The timeline of TI's rechargeable batteries?

The battery with the wire was released along with the Ti-Nspire CX, the Ti-Nspire CX CAS, and the Ti-84 Plus C Silver Edition in the early 2010s. We made a nifty little timeline that you can look at below to help illustrate this. 

Rechargeable Battery for Texas Instruments Graphing Calculators Timeline

Newer versions of the Ti-Nspire CX and Ti-Nspire CX CAS were released in late 2014 / early 2015 that used a newer battery design that no longer had the wire (or pigtail).

In the first half of 2015, the Ti-84 Plus C Silver Edition was discontinued and the Ti-84 Plus CE was announced. The Ti-84 Plus CE was the first TI handheld released to exclusively use the newer battery design (without the wire). 

In 2019, Texas Instruments released the Ti-Nspire CX II and the Ti-Nspire CX II CAS. Both of these models use the same battery without the wire, just like the Ti-84 Plus CE.
