90 Wh replacement battery for Dell G-series

This 90 Wh lithium-ion pack operates at 11.4 V and is built as a direct replacement for the original XRGXX module. It fits Dell G5 5590, G7 7590 and G7 7790 models as well as Alienware M15 R1 and M17 R1 systems listed in the compatibility data. The black finish matches the OEM appearance.

Voltage and form-factor constraints

The battery delivers a fixed 11.4 V output, so it only works in laptops designed for that exact voltage. Physical dimensions and connector layout follow the XRGXX specification, meaning it will not install in newer Alienware M15 R2, R3 or M17 R2, R3 chassis. Buyers must verify their service tag against the supported part numbers before purchase.

90 Wh capacity and runtime envelope

At 90 Wh the pack restores factory-level runtime for typical productivity workloads on the listed 15- and 17-inch machines. Heavy GPU loads such as a GTX 1070 Max-Q configuration will draw the reserve down faster, while lighter tasks extend the interval between charges. The capacity ceiling is set by the 90 Wh rating; systems requiring higher-watt-hour packs cannot use this unit.

What runtime can I expect from the 90Wh rating in a G5 5590?

A 90Wh pack at 11.4V typically delivers several hours of mixed use in a G5 5590, though actual time varies with screen brightness, GPU load and power settings.

Does the 11.4V voltage match the original Dell battery specification?

Yes, the XRGXX is rated at 11.4V, which is the same nominal voltage used by the factory batteries in the listed G5, G7 and Alienware models.
