Ready for Dell Latitude E7440

This Axiom lithium-ion battery is built for the Dell Latitude E7440 notebook. It serves as a direct replacement for the original 451-BBFV part or as a spare unit to extend working time away from a wall socket. The pack is sold new and carries RoHS certification.

Four cells for daily mobility

The four-cell design delivers standard capacity for typical office tasks such as document editing, web browsing and email. Runtime will fall short during sustained heavy workloads, long video playback or when the system drives external displays at high brightness.

Proprietary form factor fits the bay

The pack measures 12.1 inches wide, 2.6 inches deep and .3 inches high, weighing approximately 10.56 ounces. Its proprietary shape slots only into the Latitude E7440 battery bay, so it cannot be used in other Dell models or swapped into a universal drive caddy.

Questions about this item

Will the 0.3" height fit the Latitude E7440 bay without forcing the latch?

The battery measures 0.3" tall, 12.1" wide and 2.6" deep, matching the proprietary form factor Dell specifies for the Latitude E7440 so the latch engages normally.

How can I confirm the 4-cell Li-Ion pack is charging correctly after installation?

The Dell battery meter will display the charge percentage and health status; a steady increase while the AC adapter is plugged in shows the pack is accepting charge as designed.

Does the 10.56 oz package include a charger or only the battery?

Only the replacement battery is supplied; the original Dell AC adapter charges the pack, so no separate charger is required.
