Voltage and Capacity Limits

The cell delivers 11.4V and stores 53.5Wh of energy using lithium-ion chemistry. These figures define the electrical envelope your laptop expects; a different voltage or a significantly lower capacity will not run the system correctly. The black casing matches the original aesthetic but does not alter the electrical specification.

Questions about this item

Which capacity does the BTY-M492 battery provide for my MSI Sword 15 or Katana GF66?

This battery delivers 53.5Wh at 11.4V, matching the original specification for the listed Sword 15 A11U, A11UD, A11UE, Katana GF66, Pulse GL66 and Pulse GL76 models.

What does the 53.5Wh rating mean for daily runtime on a Sword 15 A11UE?

The 53.5Wh capacity restores the same energy reserve the laptop shipped with, giving you a full charge cycle equivalent to the factory battery under identical workload and brightness settings.

Does the 11.4V voltage affect compatibility with Pulse GL66 11UEK-008FR or GL76 11UEK-0301T?

No, 11.4V is the exact nominal voltage required by all listed Pulse GL66 and GL76 sub-models, so the battery fits and communicates correctly with the charging circuit.
