Questions about this item

Should I choose the 99Wh version or a lower-capacity alternative for my Alienware 17 R4?

The 99Wh capacity is the exact rating of the original 9NJM1 battery, so it restores the factory runtime for Alienware 15 R3, R4, 17 R4 and R5 models.

What does the 11.4V rating mean once the battery is installed in my Alienware 15 R3?

11.4V matches the voltage Dell specifies for the 9NJM1 pack, so the laptop's power management recognises it immediately and reports capacity correctly.

Does this pack use a proprietary Dell connector or a standard interface?

It uses the original Dell 9NJM1 connector, which plugs directly into Alienware 15 R3, R4, 17 R4 and R5 motherboards without adapters.
