Replacement battery for Latitude Rugged Extreme

The Damaite 51 Wh lithium-ion pack is built for Dell Latitude 5420, 5424 and 7424 Rugged Extreme laptops. It uses three cells at 11.4 V and carries part numbers 7WNW1, DMF8C and GK3D3. Buyers who need a different voltage or a higher cell count cannot use this unit.

Practical limits of a 3-cell 11.4 V design

A three-cell layout at 11.4 V fixes the energy ceiling at 51 Wh, so run-time is bounded by that capacity. The pack fits only the listed Rugged Extreme chassis; other Latitude models or non-rugged variants will not accept it.

The capacity that decides fit

At 51 Wh this battery matches the original specification for the 5420, 5424 and 7424 Rugged Extreme series. If your service manual calls for a different watt-hour rating, this is not the correct replacement.

Questions about this item

Should I choose the 51Wh 11.4V 3-cell version for my Latitude 5420 Rugged Extreme?

Yes — this 51Wh 11.4V 3-cell pack matches the original 7WNW1, DMF8C and GK3D3 part numbers for the Latitude 5420, 5424 and 7424 Rugged Extreme models.

What does the 51Wh rating mean for daily runtime on a Latitude 7424 Rugged Extreme?

The 51Wh capacity at 11.4V delivers the same energy budget as the factory battery, so runtime matches the original specification for the Rugged Extreme platform.

Does the 11.4V 3-cell lithium-ion interface limit charging speed on a Latitude 5424 Rugged Extreme?

No — the 11.4V 3-cell lithium-ion design is electrically identical to the OEM pack, so the laptop’s built-in charge controller manages current without any artificial cap.
