Compatible Models

This PowerWarehouse 8FCTC battery fits Alienware M15 and M17 laptops across the R3, R4, R5 and R6 revisions, including the M15 R5 Ryzen edition. It replaces OEM part numbers 8FCTC, DVG8M and P8P1P. The unit is a three-cell lithium-ion pack rated at 11.4V and 4912mAh. It is intended for owners of those specific Alienware models who need a direct replacement battery.

Sustained Operation

The lithium-ion chemistry delivers a stable 11.4V output throughout the discharge cycle, supporting consistent performance during extended work or gaming sessions. A three-cell layout balances capacity with thermal behaviour, helping the pack maintain voltage under continuous load without excessive heat buildup. The 4912mAh rating provides the energy reserve needed for long unplugged periods. Steady voltage regulation protects the laptop's power circuitry during heavy use.

Installation Notes

Replacement involves opening the laptop chassis, disconnecting the original pack and connecting this unit using the existing cable and connector. The battery matches the OEM form factor for the listed Alienware models, so no adapter or modification is required. Common issues include failing to reseat the connector fully or damaging the fragile ribbon cable during removal. Builders who need a different voltage, cell count or connector layout cannot use this pack.
