Lithium-Ion voltage and capacity limits

The battery uses Lithium-Ion chemistry rated at 14.8V and 51Wh. This voltage is fixed for the platform and cannot be changed by the user. Capacity determines runtime and will not exceed the rated 51Wh. The pack is a direct electrical match for the original specification. It does not support higher-voltage or higher-capacity configurations.

51Wh capacity decides suitability

The 51Wh rating is the single figure that determines whether this unit meets your runtime needs. If your original battery was rated at 51Wh this restores the factory capacity. Buyers who need more storage for longer unplugged sessions cannot be served by this part. No other specification overrides the capacity limit.

Does the 14.8V specification limit which Alienware 13 models can use this battery?

The 14.8V output matches the factory voltage for the listed ALW13ED‑1508 through 2608 and P56G series, so it fits those models directly.
