Dell WDXOR 42Wh 11.4V Laptop Battery

This new Dell WDXOR battery supplies 42 watt-hours at 11.4 volts across three lithium-polymer cells. It is built as a direct replacement for the original DJ1J0 pack used in multiple Latitude models. The black unit ships with two screwdrivers and an instruction sheet for straightforward user installation.

Who This Fits and Who It Does Not

The pack fits Dell Latitude 12 7280 7290, Latitude 13 7380 7390 and Latitude 14 7480 7490 series including E-series variants. It also covers the P28S P28S001 notebook line. Buyers with a Latitude 7390 2-in-1 or any model outside the listed series must choose a different battery.

Key Specification That Decides Fit

The decisive figure is the 42Wh capacity at 11.4V in a three-cell lithium-polymer format. Only systems designed for that exact voltage and watt-hour rating will recognise the pack and charge it correctly.
