MSI Laptop Battery

MSI laptop replacement batteries for Stealth, Raider, Leopard, Vector, Katana, Pulse, Creator and Summit. MSI names its laptops by a letter code and a number, and each code maps to a battery family. Every listing here is marked with its BTY code, the voltage and Wh rating where we have it, and the MSI models it fits.

Find your series letters on the label under your laptop, such as GS66 or GP76, then choose your battery below. MSI sells many models with similar names, so match the full model, including the 10SE or 11UH code at the end.

01 / Find it

Find Your MSI Laptop Battery

Read the model.
The label under the laptop gives the series and number, for example GS66 Stealth 10SE or GP76 Leopard 11UH.
Match the full name.
The code at the end, such as 10SE, 11UE or 12UH, separates generations that share a series name.
Check the rating.
The listing shows the BTY code and, where we have it, the voltage and Wh. They should equal your old battery.

If you cannot read the label, see how to find the right laptop battery or our laptop replacement batteries guide.

MSI Model Letters and Battery Codes

MSI laptop batteries carry a BTY code, and that code follows the series letters on the laptop. The letters in our listings line up like this.

GS: Stealth: GS63, GS65, GS66, GS73, GS75 and GS77. The batteries run from BTY-M6J to BTY-M6M1.
GE: Raider: GE66 and GE76. They use the BTY-M6M, the 99.99Wh battery.
GP: Leopard and Vector: GP66 and GP76. They use the BTY-M57, a 4-cell battery.
GF, GL, WF: Katana, Pulse and workstation-class models. The BTY-M492 covers the Katana, Pulse and WF series, and the BTY-M6K covers the Thin range.
WS, WP: Workstation models. They share batteries with the Stealth and Thin families, so match by model.
P, PS: Creator and Modern models. They appear under the BTY-M6L and BTY-M6M listings.

Several BTY codes begin BTY-M6. They look alike and they are not interchangeable: the BTY-M6J is 11.4V and 64.98Wh, the BTY-M6K is 11.1V and 52.4Wh and the BTY-M6L is 15.2V and 80.25Wh.

03 / Stealth

MSI Stealth Replacement Battery

The Stealth range is where an MSI owner is most likely to order the wrong battery, because the name is shared by several different packs. The GS63 and GS73 take the 11.4V BTY-M6J. The GS65 and GS75 take the larger 15.2V BTY-M6L, which MSI also uses in some Creator and Modern models. The GS77, with board number MS-17P1, has its own BTY-M6M1.

Stealth and Creator models	Battery	Rating
GS63, GS63VR, GS73, GS73VR (6RF), Stealth Pro	BTY-M6J	11.4V 64.98Wh
GS65, GS75 Stealth Thin, PS63 Modern, P65 and P75 Creator, WS65 Board numbers MS-16Q2, MS-16Q21	BTY-M6L	15.2V 80.25Wh
GS77 Stealth Board number MS-17P1	BTY-M6M1	See listing

The GS66 Stealth is covered in the Raider section below, and some GS63VR and GS73VR models appear in the Thin section. Check your exact model before you order.

04 / Raider

MSI Raider and GS66 Replacement Battery

The GE66 Raider, the GE76 Raider and Dragon Tiamat, the GS66 Stealth and the WS66 share the BTY-M6M. It is the largest battery in the collection, at 99.99Wh. That rating sits just under 100Wh, the figure at which airlines start to apply extra rules to lithium batteries, so a spare of this size is easier to travel with. Rules differ by airline and country, and the TSA publishes its guidance for lithium batteries above 100Wh.

Raider, GS66 and WS66 models	Battery	Rating
GS66 Stealth (10SE, 10SF, 11UE, 11UH) GE66 Raider (10UG, 11UG) GE76 Raider (11UE, 11UG), GE76 Dragon Tiamat (11UH) WS66 (10TM, 11UMT, 11UKT), Creator 15	BTY-M6M	99.99Wh

These laptops run hard, and a worn pack shows up as a short session away from the wall. If yours also struggles to charge, see our MSI laptop adapters.

05 / Leopard and Vector

MSI Leopard and Vector Replacement Battery

The Leopard and Vector GP66 and GP76 take one battery across three model years. The BTY-M57 is a 4-cell pack rated 15.2V, 64Wh and 4280mAh, and the listing covers the Leopard 10UE to 11UH and the Vector 12UE to 12UH. A 12th-generation Vector uses the same battery as a 10th-generation Leopard.

Leopard and Vector models	Battery	Rating
GP66 Leopard, GP76 Leopard (10UE, 10UG, 10UH, 11UE, 11UG, 11UH) Vector GP66, Vector GP76 (12UE, 12UG, 12UGS, 12UH)	BTY-M57	15.2V 64Wh 4280mAh, 4-cell

06 / Katana, Pulse, Thin

MSI Katana, Pulse and Thin Replacement Battery

MSI's mainstream gaming range uses smaller packs. The Katana GF66 and GF76, the Pulse GL66 and GL76 and the WF66 and WF76 take the BTY-M492, rated 11.4V and 53.5Wh. The Thin line, the GF63, GF65 and GF75, takes the BTY-M6K at 11.1V and 52.4Wh. The voltages differ by only 0.3V, but they are different batteries, so order by model.

Katana, Pulse and Thin models	Battery	Rating
Katana GF66, GF76 Pulse GL66, GL76 WF66, WF76	BTY-M492	11.4V 53.5Wh
GF63 Thin (8RC, 8RD, 9SC), GF65 Thin (10SDR, 9SEXR, 9SD), GF75 Thin (3RD, 8SC, 8RD, 8RC, 8RX, 9SC) GS63VR, GS73VR (7RG), GS73 8RF, WS63 8SK, WP65	BTY-M6K	11.1V 52.4Wh

07 / Summit

MSI Summit and Stealth 14 Replacement Battery

MSI's business and thin-and-light laptops use their own batteries. The Summit E14 Flip Evo A12MT and the Stealth 14 Studio A13V take the BTY-M4A, and the Summit E13 Flip Evo takes the BTY-S3B. Both sit inside a slim case, so plan the job with care.

08 / Fit it

Replacing an MSI Laptop Battery

Power down.
Shut the laptop down fully, unplug the charger and let it cool.
Open the case.
Remove the bottom screws and lift the panel with a plastic tool. Keep the screws in order. Check your warranty terms first, because some warranties do not cover damage from opening the case.
Swap the battery.
Disconnect the old connector, unscrew the pack and fit the new one in the same position. Reconnect it and check it is seated.
Close and charge.
Refit the panel, connect the charger and charge the new battery fully.

Stop using a swollen battery, or one that lifts the case or trackpad, and replace it straight away.

They are two separate listings. The BTY-M6M covers the GS66, GE66, GE76 and WS66. The BTY-M6M1 is listed for the GS77 Stealth with board number MS-17P1. Order by your model, not by the similar name.

How do I find my MSI model and board number?

The model name, for example GS66 Stealth 10SE, is on the label under the laptop. MSI board numbers such as MS-16Q2 or MS-17P1 appear in some of our listings and can be found in the system information screen or on the board.

Can I take a 99.99Wh laptop battery on a plane?

Is it the MSI battery or the charger that has failed?

If the laptop runs on the charger but shuts off when you unplug it, the battery has worn out. If it does not charge at all, test the charger first. Our MSI adapter collection covers the chargers.
