Questions about this item

What runtime can I expect from the 86 Wh rating once the battery is installed in my Alienware 17 R1?

The 86 Wh pack stores the same energy as the original, so a full charge delivers comparable run time under identical workloads and screen brightness.

Does the 14.8 V output match the charging circuit in the M18X-R3 without limiting capacity?

Yes, 14.8 V is the factory voltage for these models, so the laptop's controller charges all 8 cells to their full 5700 mAh rating.

Will this 8-cell pack fit the battery bay of an Alienware 18 R1 without modification?

The pack is built to the OEM form factor for the listed 17- and 18-inch Alienware models and uses the original screw holes and latch points.
