Genuine 90Wh replacement battery
This TOPKTEAM DT9XG battery is a new lithium-ion unit rated at 90Wh and 7500mAh with an 11.4V output. It is built as a direct replacement for Alienware Area-51M R1 and R2 models across numerous ALWA51M series configurations. The black pack matches the original form factor and fits the listed part numbers DT9XG, 7PWKV and P38E001. It restores mobile power for users whose factory cell has degraded.
Black lithium-ion pack with OEM fit
The battery uses a standard lithium-ion chemistry in a black housing shaped to the Area-51M chassis. No cables or adapters are included; the single pack slots into the existing bay using the laptop’s native connector. Alignment follows the original mounting points so installation requires only the usual service hatch removal. Buyers needing a second hot-swap pack or a different voltage will not be served by this single-unit package.
12-month warranty on a 90Wh cell
The 90Wh capacity and 11.4V rating deliver the same thermal and power profile as the original equipment under normal workloads. Lithium-ion construction keeps self-discharge low during storage and produces no audible noise in operation. A 12-month warranty covers the unit against early capacity loss. Users expecting extended runtime beyond the factory specification or active cooling features will not find them here.
