7894 mAh capacity at 11.40 V

Capacity and voltage together decide whether this pack can power the target notebook for a full work session. The 7894 mAh rating at 11.40 V matches the OEM specification for the compatible HP and Alienware Area-51M R1 and R2 systems. A different capacity or voltage would prevent correct operation or charging.

Steady output during extended unplugged use

Lithium-polymer chemistry maintains a stable voltage curve throughout the discharge cycle rather than sagging after a short burst. The pack is designed for sustained notebook workloads such as document editing, video playback or light development tasks while away from mains power. Recharge cycles are supported for the full service life of the battery.
