The HP Primary Battery is the standard battery replacement for the original battery included with each HP Business Notebook and HP Mini. It's an economical choice for users who primarily use a notebook while plugged in or docked and charge the notebook overnight when they take it home, or for users who rely on a notebook as a backup to a desktop PC.
