What this battery replaces

This 99Wh lithium-ion pack replaces Dell Alienware part numbers 9NJM1, MG2YH, 44T2R, HF25D and 01D82. It fits Alienware 15 R3, 15 R4, 17 R4 and 17 R5 models as well as P31E and P69F series laptops. Buyers with other Dell chassis or non-Alienware systems cannot use this pack.

Thermals noise and power

The battery operates at 11.4V with six cells and contains protection against short circuit, over-voltage, over-current and deep discharge. No active cooling or fan is present, so it adds no audible noise. Power draw follows the laptop's own management and the pack is rated for roughly 300 to 500 full charge cycles.

Deciding specification

Capacity is 99Wh at 11.4V in a six-cell lithium-ion format measuring 10.25 by 3.5 by 0.5 inches and weighing 1.13 lb. If your service manual lists a different voltage, watt-hour rating or physical envelope, this unit will not fit or work correctly.

Questions about this item

How do I install the 9NJM1 battery in my Alienware 17 R4 and which step do people often miss?

Remove the bottom panel, disconnect the old battery connector, fit the new 6-cell 99Wh pack, reconnect the cable, then secure the panel; the step most skip is unplugging the internal connector before lifting the old battery out.

What maintenance or replacement will the 9NJM1 lithium-ion pack need over time?

The 11.4V 99Wh cell is rated for about 300 to 500 full charge cycles; after that capacity drops enough that a replacement pack is the only practical fix.

What limit appears first when the 9NJM1 runs under sustained heavy load?

The built-in over-current and over-voltage protection circuits will throttle or cut output before the cells overheat, so the safety cut-off is the first hard limit you hit.
