Replacement Battery for Dell Alienware 15 R3 R4 17 R4 R5 P31E P69F 9NJM1 11.4V 60Wh/68Wh/99Wh High Capacity Compatible with Alienware 15 R3, 15 R4, 17 R4, 17 R5 1-Year Warranty

Why You Need This Battery

Your Dell Alienware 15 R3, 15 R4, 17 R4, or 17 R5 is a powerhouse gaming laptop built for performance. But even the best batteries degrade over time shorter runtime, unexpected shutdowns when the battery meter still reads 2030%, or the system refusing to hold a charge. Replacing it with a cheap, lowquality battery often leads to false capacity readings, swelling, or failure within months.

This 9NJM1 battery solves that problem delivering true 99Wh / 8333mAh capacity with brand new Grade A Li-ion cells. What you see is what you get.

Important 99Wh vs 68Wh Compatibility

The Alienware 15 R3 and 17 R4 series support both the 4-cell 68Wh battery and the 6-cell 99Wh battery. The 99Wh battery provides significantly longer runtime but occupies the full chassis width. Before ordering, verify your laptops battery bay has space for the 6-cell battery. Some configurations with a 2.5 hard drive may not accommodate the 99Wh version.
