Compatible CMOS Battery for LifeBook E8310

This lithium CMOS battery replaces the BIOS RTC cell on Fujitsu LifeBook E8310 motherboards. It is designed for technicians and owners who need to restore system clock and BIOS settings after the original coin cell fails. The part is a direct replacement, not a main laptop battery.

Capacity and Headroom

The battery supplies the low current required to keep real-time clock and CMOS memory alive when the laptop is unplugged. It handles normal standby durations but will eventually deplete if the machine remains without main power for extended periods. A fresh cell restores reliable boot configuration retention.

Included Single Unit

The package contains one tested CMOS battery ready for installation. No additional cables, holders or software are supplied, so the swap is a straightforward solder or socket replacement on the motherboard. This minimal bundle keeps cost low for a targeted repair.
