Genuine Dell 47 Wh battery for Latitude 7440

This 451-BBFV primary battery is a new lithium-ion unit rated at 47 Wh across four cells. It is built specifically for the Dell Latitude 7440 notebook. Buyers who need a higher-capacity pack or a different form factor should look elsewhere.

Four-cell lithium-ion chemistry limits

The four-cell design fixes the energy capacity at 47 Wh and cannot be expanded. Runtime depends entirely on the notebook's power draw and the operating system's power management. Users requiring all-day operation without charging will find the capacity restrictive.

Direct fit replacement, no tools required

The battery slots into the Latitude 7440 bay and locks with the integrated latch. No cables or screws are involved. The most common issue is forgetting to fully engage the latch, which leaves the pack loose and prevents the system from recognising it.
