Questions about this item

What does the 76 Wh rating mean for daily use on an Alienware M15 R2 or M17 R2?

It matches the original 76 Wh capacity, so you should see the same runtime you had when the laptop was new, assuming similar workload and battery health.

How does the 11.4 V specification affect compatibility with the Dell Alienware M15 R2 and M17 R2?

The 11.4 V matches the OEM voltage exactly, so the battery communicates correctly with the laptop’s power-management system and charges to the proper level.

Will this 6-cell pack fit the same bay as the original Y9M6F battery in my Alienware M15 R2?

Yes, it is built to the same 6-cell form factor and replaces the Y9M6F, CN-08K84Y and YM9KC packs used in the M15 R2 and M17 R2 chassis.
