Exactly what it says, a new battery for your calculator. After years mine dies quickly and this was very quick and easy to install.

I teach middle school and wanted reliable calculators, at a good priced, and in a distinct color so everyone knows who they belong to. They were well-packed and arrived quickly! I am so pleased with my purchase and will keep this company in mind for future needs.
