Replacement battery for Dell Latitude Rugged

This 11.4 V lithium-polymer pack is built for the Latitude 5420 Rugged, 5424 Rugged and 7424 Rugged. It delivers 51 Whr and 4342 mAh across three cells, matching the original voltage and capacity. The black casing fits the rugged chassis without modification. It is a direct swap for the factory-installed unit.

Replaces OEM part numbers 7WNW1 DMF8C

The battery substitutes Dell OEM references 7WNW1, DMF8C, 0DMF8C, CN-0DMF8C, GK3D3, 0GK3D3 and CN-0GK3D3. The upgrade is worth it when the original pack no longer holds a full charge or shows rapid discharge under load. A fresh cell restores the rated runtime for field work.

Verify the exact Latitude Rugged model before

Confirm the laptop is a 5420 Rugged, 5424 Rugged or 7424 Rugged; other Latitude models use different connectors and voltages. Check that the existing battery label lists one of the OEM part numbers above. Ensure the system BIOS is current so the new pack is recognised correctly.

Questions about this item

What space does the 3-cell 11.4V battery occupy in a Latitude 5420 Rugged?

The 3-cell lithium polymer pack is built to the original 7WNW1 form factor so it seats directly in the Latitude 5420 Rugged battery bay without adapters or shims.

Which latch or screw step is most often missed when fitting the 7WNW1 into a Latitude 5424 Rugged?

After sliding the pack home, the spring-loaded release latch must click fully; if it stays half-engaged the battery will not register and the laptop will not power on.

How do I know when the 51WHR 4342mAh pack needs replacing in a Latitude 7424 Rugged?

When a full charge no longer runs the system for its usual workload time, or the OS reports a significant capacity drop below the rated 51WHR, the cells have reached end of life.
