Replacement Battery for Latitude E7240 and E7440

The Axiom 451-BBFW-AX is a new lithium-ion notebook battery built to fit Dell Latitude E7240 and E7440 systems. It replaces the original equipment part number 451-BBFW and NCVF0. The three-cell pack supplies mobile power for everyday office tasks and travel use. RoHS certification confirms compliance with restricted-substance limits.

Proprietary Form Factor Limits Universal Use

The pack uses a proprietary size measuring 11.1 inches wide, 3.2 inches deep and .3 inches high. This shape only fits the designated Latitude chassis; it cannot be swapped into other Dell models or third-party laptops. The integrated connector and cell layout are matched to the host power-management circuitry. No adapter or bracket can make this battery compatible with a different platform.

Three-Cell Capacity for Light Workloads

At 8.96 oz the battery adds minimal weight while delivering a modest three-cell energy reserve. It comfortably handles document editing, web browsing and video playback for a typical work session. Runtime shortens quickly under sustained CPU load, discrete graphics activity or high screen brightness. Users needing all-day autonomy away from mains power should plan for a mid-day recharge.

Questions about this item

Which Axiom battery part number replaces Dell 451-BBFW or NCVF0 for a Latitude E7240 or E7440?

This unit carries MPN 451-BBFW-AX and is listed as compatible with OEM part numbers 451-BBFW and NCVF0 for Latitude E7240 and E7440 notebooks.

What runtime can I expect from the 3-cell lithium-ion pack in a Latitude E7240?

The pack uses three lithium-ion cells in a proprietary form factor; actual runtime depends on the notebook's power draw, screen brightness and workload rather than a fixed hour rating.

Does the proprietary connector match the original Dell battery interface in the E7440?

Yes, the battery is built to the same proprietary size and connector layout as the OEM unit so it fits the Latitude E7240 and E7440 battery bay without adapters.
