Genuine 54Wh replacement for Latitude 7420 7440 7450

This TOPKTEAM 3RNFD battery delivers 54Wh at 7.4V using lithium-ion cells in a black housing. It fits Dell Latitude E7420 E7440 E7450 and the listed Precision 3520 3530 models. Buyers restoring original runtime on these 14-inch business laptops will find a direct mechanical and electrical match.

Steady output through a full workday

Lithium-ion chemistry maintains consistent voltage across the discharge curve so the system does not throttle early under sustained load. The 54Wh capacity supports typical office workloads across a standard shift without the sharp drop-off seen in aged cells. Thermal behaviour stays within the laptop's original cooling design.

Questions about this item

Does the 54Wh 7.4V battery run hot or drain quickly when the Latitude 7440 is used all day?

The 54Wh 7.4V lithium-ion pack is rated for a full day of typical office work on a Latitude 7440; heat stays low because the cell chemistry matches the original Dell specification.

What must already be in the laptop for this 3RNFD battery to fit and work?

The laptop must use the Dell 3RNFD / 34GKR / PFXCR form factor — found in Latitude E7420, E7440, E7450, 7250, 7460 and the listed 5280, 5288, 5480, 5488, 5490, 5491, 5495, 5580, 5590, 5591, 3520, 3530 models.

Will the 3RNFD pack charge correctly in an older Latitude E7250 that originally shipped with a 42Wh battery?

Yes — the 7.4V 54Wh pack shares the same voltage and connector as the E7250 original, so the system charges it normally and reports capacity accurately.
