Fits Directly into Existing Chassis

The battery matches the original voltage and connector layout so it slots into the same bay without adapter cables or firmware updates. It restores full mobility to the listed Alienware notebooks and frees the user from relying on the AC adapter during travel or power outages. No additional hardware is required beyond the laptop itself.

Steady Output Through Extended Sessions

Lithium-ion chemistry delivers a stable 11.4V rail across the discharge curve, keeping the system from throttling during long gaming or rendering workloads. The 99Wh capacity supports multi-hour runtimes under continuous load rather than short bursts. High recycle life means the pack retains usable capacity after many charge cycles.
