Direct replacement for Latitude E6400 XFR

This 6-cell lithium-ion battery carries Dell part number 312-0917 and is rated at 56 WHr. It is built as a direct replacement for the Latitude E6400 XFR notebook. The unit is new and sourced from undeployed systems without original retail packaging.

Simple swap with proprietary connector

Installation consists of releasing the old pack and sliding this one into the same bay until it clicks. The proprietary form factor prevents use in any other model, so verifying the exact part number before purchase avoids a mismatch.

Capacity fixed by chemistry and form factor

The 56 WHr rating reflects the energy available from six lithium-ion cells in this specific enclosure. Runtime will vary with workload, screen brightness and power settings, and the pack cannot be upgraded beyond its factory capacity.
