Replacement Battery for Alienware M17x

This 90Wh lithium-ion pack replaces the original BTYVOY1 unit in Alienware M17x R3 and R4 notebooks. It delivers 11.1V and matches part numbers 318-0397 and 451-11817 so the laptop recognises it without BIOS errors. The black housing fits the existing battery bay exactly as the factory component did.

Owners of Alienware M17x R3

Buyers with other Alienware chassis or different laptop brands cannot use this pack because the connector and form factor are model-specific. It is also unsuitable for anyone requiring a higher capacity than 90Wh or a different voltage.

90Wh capacity at 11.1V

The 90Wh rating is the single figure that determines whether this battery meets your runtime expectations. Check your original battery label; if it shows 90Wh and 11.1V this part is a direct match.
