Drop-in replacement for Alienware 17 R4

This NShi 11.4 V 99 Wh lithium-polymer battery replaces Dell part numbers 9NJM1, 0546FF, 0HF250, 44T2R, HF250 and MG2YH. It is built new and carries a 12-month warranty. The unit fits Alienware 15 R3 and 17 R4 series chassis including ALW17C-D1748, ALW17C-D1758 and related sub-models. Verification of the original part number before purchase ensures correct fit.

Suits owners needing a direct swap

The battery suits users whose Alienware 15 R3 or 17 R4 no longer holds charge and who want a like-for-like replacement without adapter cables or firmware work. It is not for laptops outside the listed Dell part-number range, nor for systems that require a different voltage or connector layout. Buyers who cannot confirm the old battery part number should look elsewhere.

99 Wh capacity for extended unplugged use

At 99 Wh the pack delivers the same energy rating as the original Dell HF250 series cell, supporting long gaming or work sessions away from mains power. Runtime scales with workload; heavy GPU loads will deplete the battery faster than light productivity tasks. The 11.4 V output matches the factory specification, so the power-management subsystem reports capacity accurately.

Questions about this item

Which part numbers on my current Alienware battery confirm this 9NJM1 replacement will fit?

Check your old battery for 9NJM1, 0546FF, 0HF250, 44T2R, HF250 or MG2YH; any match means this 11.4 V 99 Wh pack is the correct replacement.

Will this 99 Wh pack charge and report capacity correctly through the Alienware 17 R4’s original power-management firmware?

Yes, it uses the same 11.4 V lithium-polymer chemistry and connector layout, so the laptop’s built-in controller recognises it and reports charge levels normally.

After installing the battery, how do I verify the 99 Wh capacity is being reported in Windows?

Open Command Prompt and run powercfg /batteryreport; the generated HTML will show a design capacity of 99 Wh if the pack is communicating correctly.
