Introduction

The TI BA II PLUS Calculator has a special function in financial calculation which other calculators don’t have. For students who major in accounting and finance, using their financial calculator frequently will inevitably run out the batteries more quickly. If students don’t know to to replace the batteries, they may just throw away the used calculator then buy a new one. They would not only waste $40, but the unnecessary consumption of plastic can damage our environment. We all know that plastic pollution causes harm to humans, animals and plants through toxic pollutants.

Knowing how to replace the battery is necessary to maintain your calculator. This guide shows the steps to replace the battery of your TI BA II PLUS Calculator.

It’s amazing that this calculator can break. I am an accountant student in college and despite modern technologies and the rather powerful functionality of modern smartphones, I like to use just such a calculator for financial calculations.
