Replacement Battery for Latitude E7420 E7440 E7450
This 11.1 V 34 Wh lithium-ion battery replaces the original power pack in Dell Latitude E7420 E7440 E7450 Ultrabook 7000 Series laptops. It matches the factory voltage and capacity so the system recognises it without BIOS updates. The unit is new and carries CE FCC RoHS safety certifications. It suits owners who need a direct swap for a worn or failed internal battery.
Upgrading from a Depleted Original Cell
When the original cell no longer holds a useful charge this replacement restores the laptop’s untethered runtime to its design level. The jump is worth it if the machine otherwise meets your needs but shuts down early or refuses to run on battery alone. It does not increase capacity beyond the stock 34 Wh rating so buyers who want more storage or longer life than the factory specification should look elsewhere.
Steady Output During Extended Use
The lithium-ion chemistry delivers a stable 11.1 V rail throughout the discharge curve rather than a sharp voltage drop near empty. This behaviour keeps the ultrabook running consistently during long sessions away from mains power. The pack is built for daily charge cycles and includes protection circuitry to guard against overcharge and deep discharge. It is not intended for systems that require a higher voltage or different form factor.
