CMOS Battery for HP EliteBook Folio 9470m / 9480m Series

The CMOS battery for HP EliteBook Folio 9470m and 9480m is a small 3V RTC (Real Time Clock) battery used to retain BIOS settings, system clock, and hardware configuration when the laptop is powered off. Unlike a standard loose coin cell, this battery comes in a wired 2-pin connector with a protective sleeve, commonly using a CR2032 or CR2025 cell inside depending on the variant. It is compatible with HP EliteBook Folio 9470m and 9480m models and helps resolve issues such as incorrect system time, BIOS reset errors, and startup configuration loss. In some configurations, the same type is referenced under part number 702853-001. It is a small but essential internal component that ensures stable BIOS memory retention even when the main battery is removed or discharged.
