Purpose and audience

This replacement battery fits Dell Latitude 5420 Rugged, 5424 Rugged and 7424 Rugged laptops. It is a new 3-cell lithium-ion unit rated at 11.4 volts and 51 watt-hours for users who need a fresh power source for those specific models.

Interface limits

The pack connects through the laptop’s proprietary battery bay, so no standard connector or charging protocol is exposed. Capacity is fixed at 4342 milliampere-hours and the cell chemistry is lithium-ion; higher-capacity or alternative-chemistry options are not available for this form factor.

Pre-purchase checks

Verify that the original battery part number matches one of the listed OEM codes such as 7WNW1, GK3D3 or DMF8C before ordering. Confirm the laptop model label reads exactly Latitude 5420 Rugged, 5424 Rugged or 7424 Rugged, as other Latitude variants use different battery shapes.

Questions about this item

Which part number should I pick for my Latitude 5420 Rugged?

All listed part numbers — 7WNW1, DMF8C, 0DMF8C, CN-0DMF8C, GK3D3, 0GK3D3, CN-0GK3D3, 1Y62C, 451-BCHS, 451-BCHV — refer to the same 11.4V 51Wh 3-cell battery, so any one matches your laptop.

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

The 51 watt-hour capacity (4342mAh at 11.4V) typically delivers several hours of mixed use on a Latitude 7424 Rugged; actual runtime depends on screen brightness, workload and power settings.

Does the 11.4V specification limit charging speed or compatibility?

The 11.4V output matches the original Dell specification, so the battery charges at the standard rate and works with the laptop’s built-in power management without any voltage mismatch.
