Direct replacement for Alienware M15 R2 and M17 R2

This 76Wh lithium-polymer battery replaces the original Y9M6F unit in Dell Alienware M15 R2 and M17 R2 laptops. It matches the factory 11.4V specification and 6334mAh capacity. The black pack fits the P87F and P41E chassis variants without modification.

Upgrades worn or failed original cells

The pack restores full runtime when the original battery no longer holds charge or reports a service alert. Swapping it eliminates throttling caused by an aged pack that cannot deliver peak current. The improvement is immediate once the new cells are calibrated.

76Wh capacity covers typical mobile workloads

At 76Wh the battery supports several hours of office tasks, web browsing or video playback on the 15-inch or 17-inch models. Heavy gaming or sustained GPU loads will drain the pack faster and require AC power for extended sessions.
