This 99Wh lithium-polymer battery fits Dell Alienware 15 R3, 15 R4, 17 R4 and 17 R5 models along with the P31E, P69F and ALW17C series. It operates at 11.4V across six cells and matches part numbers 9NJM1, 44T2R, MG2YH and HF25D. Buyers needing a different voltage or form factor should look elsewhere.

Slim 6-cell pack with included tools

The pack measures roughly 10.25 by 3.5 by 0.5 inches and weighs about 1.13 lb, matching the original chassis footprint. A screwdriver set ships in the box so the swap can be done without sourcing extra bits. Protection circuitry covers short circuit, over-voltage, over-current and discharge events.

Restores runtime on ageing 15-inch

Designed for about 300 to 500 charge cycles, it replaces depleted OEM units in the listed Alienware and Precision workstations. The upgrade is worthwhile when the original pack no longer holds a full day’s charge or triggers capacity warnings. Users with non-listed Dell models or newer chassis revisions will not be served by this part.
