Dell Latitude Battery Replacement

This 42Wh lithium-ion battery replaces the original DJ1J0 cell in Dell Latitude 12, 13 and 14 7000-series laptops. It matches the 11.4V specification and fits models including the 7280, 7290, 7380, 7390, 7480 and 7490 families. Buyers needing power for a different voltage or a higher capacity should look elsewhere.

Simple Swap With One Common Pitfall

Installation requires only a small Phillips screwdriver to remove the bottom cover and disconnect the old pack. The connector is keyed, so it cannot be inserted backwards, but the 7390 2-in-1 uses a different internal layout and this part will not fit that chassis. Rushing the screw sequence can strip the fragile palm-rest threads.

42Wh Capacity Defines Runtime

The 42 watt-hour rating determines how long the system runs between charges; it is the single figure that confirms this is the correct replacement for the factory pack. Systems originally shipped with a different capacity will see altered battery life, and no other specification in the data changes that outcome.

Questions about this item

How can I confirm the 11.4V 42Wh battery is working correctly after installing it in my Latitude 7490?

The system should recognise the genuine Dell part, charge to full capacity, and report normal battery health in the BIOS or Dell Power Manager without unexpected shutdowns.

What is included with the DJ1J0 battery and do I need any extra parts for a Latitude 7380?

Only the battery itself is supplied; no tools, screws, or cables are included, and none are required for installation.

Which DJ1J0 version fits a Latitude 13 7390 but not the 7390 2-in-1?

This DJ1J0 unit is listed for the standard Latitude 13 7380 and 7390 models and is explicitly noted as not compatible with the 7390 2-in-1 variant.
