Replacement battery for Alienware M11x and M14x

This 14.8 V lithium-ion pack replaces the original PT6V8, T7YJR and 8P6X6 cells in Alienware M11x, M11xR2, M11xR3, M14x and M14xR2 notebooks. It delivers 63 Whr from four cells rated at 4257 mAh. The unit is new and carries CE, FCC and RoHS safety certification.

Upgrading from a depleted or swollen OEM pack

Swap the old battery when runtime has dropped sharply or the chassis shows physical bulging. The replacement restores the factory voltage and capacity without modifying the laptop. The jump is worth it when the original no longer holds a usable charge through a typical work session.

Fits the existing battery bay and charging circuit

The pack slides into the standard bay and connects to the stock motherboard header, requiring no adapter or BIOS update. It frees the user from permanent mains tethering and restores portable operation. No additional hardware or configuration is needed beyond the normal battery swap procedure.

Questions about this item

Will the 14.8 V 63 Whr pack fit the Alienware M11x R2 battery bay?
