Direct replacement for Latitude E6400

This lithium CMOS battery restores the real-time clock and BIOS settings on a Dell Latitude E6400 laptop. It is a direct swap for the original coin cell on the motherboard. The part arrives new and tested, ready for immediate installation. Technicians and owners of this model can use it to fix date drift or configuration loss.

Single coin cell restores BIOS data

The battery supplies the low current needed to keep CMOS memory alive while the main power is off. One cell provides enough capacity for years of typical standby time. It does not power the laptop itself and cannot replace a main battery pack. When the cell finally depletes, the system clock will reset again.

Fits motherboard holder, frees main battery

The coin cell seats in the standard motherboard holder without soldering or adapters. No extra cables, brackets or drivers are required for the swap. Replacing it returns the BIOS to reliable operation and leaves the main battery bay untouched for its own pack.
