Casio FX-991ES Plus Battery Replacement

소개

This guide demonstrates the process of replacing the battery for a Casio FX-991ES Plus calculator. The battery will need to be replaced when a dim or distorted display is noticed, or when the calculator stops working. The calculator is equipped with a solar cell that can provide power to the device, but if the battery becomes old or bloated, it should be replaced in order to prevent leakage that might damage the calculator. Although this calculator uses two-way power, it is inconvenient to depend on having to charge the built-in solar cell when the battery is dead.
