11.4 V 99 Wh replacement battery
This lithium-polymer pack supplies 11.4 V and 99 Wh through four cells. It fits Dell Alienware 15 R3 R4 and 17 R4 R5 notebooks including the ALW17C-D1738, D1748, D1758, D1848, D2738, D2748, D2758 and R1748 series. The unit is new and carries CE, FCC and RoHS certification. Owners of those laptops who need a fresh power source will find a direct match.
Replaces original Dell part numbers
The battery substitutes Dell part numbers 9NJM1, MG2YH, 0MG2YH, 01D82, HF250, 0546FF and 44T2R. If the original pack no longer holds charge or shuts down the system when unplugged, this unit restores full mobile operation. The jump is worth it when the old cell count drops below usable runtime or the firmware reports a permanent failure. Machines outside the listed Alienware models are not supported.
Simple internal swap with firmware reset
Installation requires opening the chassis, disconnecting the old pack and connecting the new one using the same cable. Most issues arise when the system does not recognise the fresh battery; a full discharge to 0 % followed by an uninterrupted charge to 100 % usually forces the firmware to recalibrate. If the laptop still dies at 60 % or refuses to charge, repeat the calibration cycle or reseat the connector.

Questions about this item
Does the 11.4V 99Wh pack fit the Dell Alienware 15 R3 chassis without modification?
The battery is built to the original 4-cell form factor for Alienware 15 R3, R4 and 17 R4, R5 series, so it seats in the factory bay using the existing screw points and connector.
What is the correct first step after plugging in the 9NJM1 connector?
Power on the notebook, enter BIOS and run the battery calibration cycle; skipping this step often leaves the gauge stuck at 60 % or shows a false 0 % reading.
When should I expect the 8820 mAh capacity to drop below usable levels?
The cells are rated for up to 500 full recharge cycles; after that point runtime will noticeably shorten and a replacement will be needed.
