Capacity Decides Fit

Rated at 4623mAh and 54Whr, this battery matches the original energy specification. Buyers who need longer runtime than 54Whr provides should look for a higher-capacity alternative if their chassis supports it.

Questions about this item

Is this the only capacity available for the 2X1V9 battery?

This GreenTech 2X1V9 replacement is offered as a 3 cell lithium-ion pack rated at 4623mah and 54WHR, matching the OEM specification for the listed Dell models.

What does the 54WHR rating mean for daily runtime on a Latitude 5440?

The 54WHR capacity restores the original factory runtime; actual hours depend on screen brightness, workload and power settings but the energy store is identical to the Dell 2X1V9 it replaces.

Does the 11.4V voltage match the Dell 803W6 connector and charging circuit?

Yes, the 11.4V output and 3 cell design are engineered to the same electrical spec as Dell part 803W6, so the laptop's charging controller recognises and manages it normally.
