Compatible Dell Latitude Rugged models

The NShi 7WNW1 is a new replacement battery built for Dell Latitude 5420 Rugged, 5424 Rugged and 7424 Rugged Extreme laptops. It replaces OEM part numbers including GK3D3, DMF8C and 451-BCHS. The 3-cell lithium-ion pack delivers 11.4V and 51Whr capacity for mobile professionals who need reliable power in demanding environments.

Sustained capacity and cell balance

Rated at 4473mAh, the three lithium-ion cells maintain consistent voltage during extended field use rather than dropping off after a short burst. The chemistry supports steady discharge across a full work shift, so the rugged notebook remains operational throughout long deployments without unexpected shutdowns.

Thermals and power efficiency

Lithium-ion construction generates minimal heat during normal charge and discharge cycles, keeping the battery bay within safe thermal limits. The pack draws only the current required by the system, reducing unnecessary power loss and helping the laptop’s cooling system stay quiet during typical office or field operations.

Questions about this item

Does the 11.4 V 51 Whr battery run hot during all-day use?

The 3-cell lithium-ion pack is rated at 11.4 V and 51 Whr, matching the original thermal envelope for the Latitude 5420, 5424 and 7424 Rugged models.

Must I already own a Dell Latitude 5420, 5424 or 7424 Rugged for this battery to work?

Yes — it replaces OEM part numbers 7WNW1, GK3D3, DMF8C, 1Y62C, 451-BCHS and 451-BCHV only in those three Rugged chassis.

Will the 4473 mAh cell capacity match the runtime of the original battery in my older Latitude 5424 Rugged?

The 4473 mAh rating equals the OEM specification, so runtime on a 5424 Rugged should be the same as the factory pack.
