Replacement Battery for Alienware 15 and 17

This 99Wh lithium-ion pack is built for Dell Alienware 15 R3, R4 and 17 R4, R5 series notebooks. It restores full mobile runtime when the original cell pack has worn out. The six-cell design matches the factory voltage of 11.4V and fits the existing bay without modification.

Who This Suits and Who Should Look Elsewhere

Owners of the listed Alienware models who need a direct swap will find a precise fit and a one-year replacement guarantee. Buyers with other Dell chassis, different voltage requirements or a desire for a higher-capacity pack than 99Wh should look elsewhere.

Capacity and Headroom

The 99Wh rating delivers extended operation for everyday workloads, media streaming and light creative tasks on a single charge. Heavy gaming sessions or sustained maximum CPU and GPU loads will deplete the pack more quickly, so keep the AC adapter handy for long sessions.
