Replacement battery for Area-51M

This NShi DT9XG battery replaces the original power pack in Alienware Area-51M R1 and R2 laptops. It is a 9-cell lithium-ion unit rated at 11.4V with a capacity of 7895mAh and 90WHR. The part matches OEM numbers DT9XG, 0KJYFY, CN-0KJYFY and 7PWKV.

Owners of compatible Alienware models

The battery fits Area-51M R1 and R2 systems that require an 11.4V 9-cell pack. It is not suitable for other Alienware chassis, different voltage requirements or smaller cell-count configurations. Buyers needing a higher capacity than 7895mAh or a different form factor should look elsewhere.

11.4V 9-cell voltage and capacity

The 11.4V 90WHR specification determines whether this unit matches the laptop's power circuitry. Verify the original battery label shows 11.4V and 9 cells before purchase. A mismatched voltage or cell count will prevent correct operation.

Questions about this item

How can I confirm the 11.4V 7895mAh battery is working correctly after installing it in my Area-51M R1?

The system should detect the 9-cell pack, show 11.4 volts in the BIOS or OS power meter, and run without unexpected shutdowns under load.

What comes with the DT9XG battery and what must I source separately for my Area-51M R2?

The box contains the 90WHR replacement battery only; you reuse the existing screws, cables and any thermal pads from the old pack.

Which version of the GreenTech DT9XG should I choose for an Alienware Area-51M R1 versus R2?

The single DT9XG part replaces OEM numbers 0KJYFY, CN-0KJYFY and 7PWKV and fits both R1 and R2 models.
