Replacement battery for MSI GF63 and GF75 Thin

This 11.4V lithium-ion pack delivers 52.4Wh and 4500mAh across three cells. It replaces OEM part numbers BTY-M6K, MS-17B4 and several related codes. The unit fits a long list of GF63, GF75 Thin, GS63VR and GS73 models. Buyers with other MSI chassis or different voltage requirements cannot use this battery.

Sustained discharge and circuit protection

Rigorous testing confirms correct voltage, stable current and low self-discharge during extended use. Built-in protection guards against overcharge, over-discharge and short circuits. The 52.4Wh rating supports typical workloads without sudden voltage sag. Systems that demand higher watt-hour capacity or a different cell count will not be compatible.

Black three-cell housing with CE FCC RoHS marks

The black casing matches the original form factor and locks into the existing battery bay without adapters. Connectors align with the motherboard header for a direct fit. Certificates cover CE, FCC and RoHS safety standards. Laptops that use a four-cell or six-cell design, or a different connector keying, cannot accept this pack.

Questions about this item

Does the 3-cell 11.4V 52.4WHR battery run hot or draw extra power during all-day use?

The 3-cell lithium-ion pack is tested for stable current, low self-discharge and correct voltage, so it should not generate excess heat or draw more power than the original 52.4WHR unit.

Must my MSI laptop already have the BTY-M6K or MS-17B4 part installed for this replacement to fit?

Yes — the battery replaces OEM numbers BTY-M6K, MS-17B4, MS-16K3, MS-16W1, MS-16R4, MS-16R1, MS-16R3, MS-17F1, MS-17F2 and MS-17B7, so one of those must be the original part in your machine.

Will this 11.4V 4500mAh pack work in an older MSI GS63VR 7RG Stealth Pro that originally used a different battery model?

The compatibility list includes GS63VR 7RG Stealth Pro and GS63VR 7RG-005 among supported models, so the 11.4V 4500mAh pack is designed to work in those older systems.
