A: I put it into the calculator and just charge it normally by connecting the usb cable to the TI calculator.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit
*by J***R on December 7, 2025*

Perfect fit and fixed my Ti-Nspire CAS CXII which would not hold a charge.

### ⭐⭐⭐⭐⭐ Highly recommended
*by D***S on November 14, 2025*

Good replacement battery for TI84 calculator. Brought it back to life. Works like new.

### ⭐⭐⭐⭐⭐ Did the trick!
*by S***O on February 17, 2025*

My TI-84 plus CE calculator was acting up after not using it for a whole semester. When I charged it, it kept flashing and could not hold a battery. Since my 1 year warranty was already up, I took a chance buying this replacement. As you can see in the photo, no more flashing and my calculator is functioning properly again. I did not need to charge the calculator after installing the replacement battery because it had some power in it as it was delivered.
