Questions about this item

What does the 76 WHr capacity mean for actual runtime on an Alienware m15 R2?

The 76 WHr rating indicates the total energy the battery stores; real-world runtime on an Alienware m15 R2 depends on screen brightness, CPU load and power-profile settings.

How does the 11.4 V rating relate to the laptop's charging circuit?

The 11.4 V output matches the original design voltage for the Alienware m15 R2 and m17 R2 charging circuits, so the system regulates charge current normally.

Will the six-cell pack fit the existing battery bay without modification?

Yes, the six-cell Y9M6F is built to the same physical dimensions as the factory battery for Alienware m15 R2 and m17 R2, so it seats directly in the standard bay.
