CASIO fx-300ES Plus Scientific Calculator Battery Replacement

はじめに

This guide shows an easy step-by-step process on how to replace the battery of a CASIO fx-300ES Scientific calculator. A low battery is determined by a dim display, uneven contrast, or figures failing to appear right when the calculator is turned on. A battery can cause leakage if dead which causes malfunction. The battery life is approximately three years based on the usage of one hour per day, and once that is exceeded the battery dies. Be sure to note the orientation of the battery for replacement. Avoid using a metal spudger as it can cause damage.
