Replacement battery for Alienware M11x

This 14.8V lithium polymer battery replaces Dell originals such as PT6V8, P18G and DKK25 across the M11x, M11xR1, M11xR2, M11xR3, M14xR1 and M14xR2 families. It delivers 4000 mAh and 59 Wh to restore run time on compatible notebooks. Built-in short-circuit, overheat and overload protections maintain safe operation. The unit is new and carries a one-year warranty from the manufacturer.

Straightforward swap with model verification

Installation follows the standard Alienware battery bay procedure: power down, release the latch, swap the pack and lock it back in place. The critical step is confirming that your original battery carries one of the listed part numbers and shows 14.8V on its label; the M14xR3 and M14xR4 are explicitly excluded and will not accept this pack. No tools beyond a fingertip latch are normally required.

Check your original battery label before ordering

Locate the part number on your existing battery and match it against the supported list such as 0DKK25, 0PT6V8, 0T7YJR, 312-0984, 8P6X6 or KR08P6X6. Verify the printed voltage reads 14.8V to avoid a mismatch. This product is not for buyers who need a pack for the M14xR3, M14xR4 or any model outside the compatibility table.
