Understanding the TI-84 Plus Battery

When I first got my TI-84 Plus calculator, I didn’t pay much attention to the battery. However, I soon realized that having a reliable power source is crucial for my studies. The TI-84 Plus typically uses either four AAA batteries or a rechargeable battery pack, and understanding these options is essential for making the right choice.
