11.4V 53.5Wh replacement battery

This new lithium-ion battery replaces part numbers BTY-M492 and 3ICR6/71/74 in compatible MSI laptops. It delivers 11.4 volts and 53.5 watt-hours of capacity in a black housing. The unit is designed for owners of Sword 15, Katana GF66, Pulse GL66, Pulse GL76 and Bravo 15 models who need a direct power-source swap.

Check your exact model code before ordering

Verify that your laptop appears in the supported list such as Sword 15 A11U, A11UD or A11UE, Katana GF66 12Ux, or the many Pulse GL66 and GL76 sub-variants. Confirm the original battery carries the BTY-M492 or 3ICR6/71/74 part number printed on its label. This battery will not fit laptops outside the named series or those using a different voltage or connector.

Fits inside the existing battery bay

The pack slots into the standard compartment without extra cabling or mounting hardware. It restores mobile operation for the supported MSI machines and frees you from permanent mains tethering. No additional chargers or adapters are required beyond the laptop's original power supply.

Questions about this item

Does the BTY-M492 package include any tools or cables, or must I buy them separately?

The box contains only the 11.4 V 53.5 Wh lithium-ion battery; no screwdrivers, opening tools or cables are supplied, so you will need a small Phillips screwdriver to swap the old pack.

My laptop is a Pulse GL66 11UEK-008FR — is the BTY-M492 the correct version?

Yes, the BTY-M492 replaces part numbers BTY-M492 and 3ICR6/71/74 and is listed for the Pulse GL66 11UEK-008FR among many other Sword 15, Katana GF66 and Pulse GL66/GL76 models.

What does the 53.5 Wh rating mean for daily run-time on a Sword 15 A11UE?

At 11.4 V the pack stores 53.5 Wh; a typical Sword 15 drawing 20–25 W will run roughly 2–2.5 hours on a full charge, varying with screen brightness and workload.
