Who This Suits and Who Should Look Elsewhere

Owners of the listed Alienware models who need a direct-replacement cell with matching voltage and capacity will find this unit compatible. Buyers with other Dell series or non-Alienware chassis cannot use this battery. Users wanting a higher-watt-hour pack or a different form factor should seek an alternative.

Check Your Current Battery Before Ordering

Open the back cover and verify the existing battery carries one of the listed part numbers. Confirm the label reads 14.8V and 5605mAh or 86Wh. Ensure the connector orientation matches the original unit. Follow the break-in routine of three to four full charge cycles down to five to ten percent for best results.

Questions about this item

Do I need to verify the 2F8K3 part number on my existing battery before installing this 14.8V 5605mAh unit?

Yes, the supplier advises opening the back cover to confirm the battery model and capacity match 2F8K3 or 02F8K3 before purchase.

Will this 86Wh replacement fit the same bay as the original battery in my Alienware M18X R3?

The battery is listed as compatible with Alienware 18, 18X and M18X R3 models, so it should occupy the original bay.

How can I confirm the new 14.8V 5605mAh battery is working correctly after the first few charge cycles?

Perform 3‑4 full charge and discharge cycles down to 5‑10 % as recommended; the system should then report the full 86Wh capacity.
