Check your exact model and voltage

Verify that your laptop appears in the supported list before ordering. Confirm the original battery shows 11.4V and 90Wh on its label. Ensure the part number matches one of the listed replacements to avoid fitment issues.

Steady output during long sessions

The lithium-ion chemistry maintains consistent voltage across extended workloads rather than dropping sharply after a brief burst. A 12-month warranty covers the pack for regular daily charging cycles.

Questions about this item

Does the package include any tools or cables, or is it only the battery itself?

The package contains one 11.4V 90Wh lithium-ion battery in black; no tools, cables or adapters are included.

My Alienware G5 15 5590 originally had a 54Wh or 65Wh pack — which capacity should I choose?

This replacement is a single 90Wh unit that replaces both the 54Wh and 65Wh variants across the G5 15 5590, G7 7590, G7 7790, M15 R1 and M17 R1 lines.

What does the 90Wh rating mean for everyday use on an M15 R1?

The 90Wh capacity stores more energy than the factory 54Wh or 65Wh packs, so the laptop runs longer on a single charge under the same workload.
