CMOS Battery for Fujitsu LifeBook E8310

This lithium coin cell replaces the motherboard CMOS battery in the Fujitsu LifeBook E8310. It maintains the real-time clock and BIOS settings when the main power is disconnected. The part is supplied new and tested before shipping. It is intended for laptop motherboards, not the main laptop battery pack.

Replaces a dead or leaking original CMOS cell

When the system clock resets or BIOS configuration is lost at every boot, the original CR-type cell has likely failed. Swapping it restores persistent firmware settings and correct timekeeping. The upgrade is only worthwhile if the existing battery no longer holds a charge; a functioning cell does not need preventive replacement.

Limited to CMOS RTC backup function only

This battery cannot power the laptop itself or charge any other component. It provides a low current solely for the real-time clock and CMOS memory on the motherboard. Compatibility is restricted to the specific LifeBook E8310 model; it will not fit other laptop series or desktop mainboards.
