Compatible replacement battery

The NShi BTY-M492 is a new GreenTech lithium-ion battery built to replace the original MSI BTY-M492 unit. It fits MSI Sword 15 A11U series, Pulse GL66 and GL76, and Katana GF66 and GF76 laptops. The pack uses three cells rated at 11.4 V and 4700 mAh for 53.5 Wh of capacity. Buyers who need a higher-capacity pack or a different form factor cannot use this model.

Voltage and capacity limits

The battery delivers a fixed 11.4 V output and 53.5 Wh energy rating, so runtime is bound by those figures. A three-cell lithium-ion design means the physical size and connector layout match the OEM specification exactly. Systems that require a different voltage, a larger cell count or a proprietary smart-battery protocol will not work with this replacement.

Check your laptop model and connector

Verify that your device appears in the supported list: Sword 15 A11U, A11UD or A11UE, Pulse GL66 or GL76, Katana GF66 or GF76. Confirm the original battery carries part number BTY-M492 and shows the same 11.4 V rating. Ensure the battery bay and connector orientation match the three-cell layout before ordering.

Questions about this item

Which GreenTech BTY-M492 battery version fits my MSI laptop?

This single BTY-M492 model replaces the OEM part for MSI Sword 15 A11U, A11UD, A11UE, Pulse GL66, GL76, Katana GF66 and GF76 — choose it if your machine appears in that list.

What does the 53.5 Wh rating mean for daily runtime?

The 53.5 Wh capacity combined with 11.4 V and 4700 mAh delivers a typical full charge for the listed MSI models; actual hours depend on screen brightness, GPU load and power-profile settings.

What connector standard does the BTY-M492 use and what does it limit?

It uses the proprietary MSI multi-pin connector built into Sword, Pulse and Katana chassis, so it only fits those exact models and cannot be adapted to other brands.
