MSI 16H2 BTY-M6F Replacement Battery 11.4V 4100mAh

MSI GS60 / 16H2 Series — 11.4V Li-Polymer Replacement Battery (BTY-M6F)

This is an 11.4V, 4100mAh (46.74Wh) lithium-polymer replacement battery for MSI GS60 and 16H2 series laptops. It fits models including the GS60 2PC-010CN, GS60 2PC-279XCN, and over two dozen related variants that share the BTY-M6F specification. Install it when the original cell no longer holds a usable charge or fails to register correctly in the OS.

• GS60 and 16H2 platform fit: These models share the same 11.4V three-cell Li-Polymer rail, BTY-M6F connector pinout, and BMS handshake protocol. Any variant in this family pulling from that same power architecture accepts this cell without modification.
• Bench tested on actual hardware: We cycled this battery on a GS60 unit and confirmed the BMS handshake completed correctly — the OS recognised the cell, charge current ramped normally from cold, and the protection circuit tripped at the correct low-voltage threshold.
• Post-install discharge cycle on MSI laptops: After fitting this cell, run the laptop down to hibernate cutoff under normal load, then charge uninterrupted to 100%. This forces the BIOS battery learn cycle to reset against the new cell's actual capacity curve and clears the false poor-health warning that appears after every cell swap on MSI firmware.

BIOS reporting battery health as poor immediately after fitting a new BTY-M6F

MSI firmware stores learned capacity data from the previous cell in non-volatile memory. When a new cell goes in, that stored data no longer matches the actual chemistry, so the BIOS flags a health warning even though the new battery is fine. The fix is not a setting change — it is a full recalibration cycle. Discharge to hibernate cutoff, charge to 100% without interruption, and the BIOS will overwrite the stale EEPROM data with values from the new cell.

This is a voltage cliff issue, not a faulty cell. The fuel gauge IC is still using the old cell's discharge curve, so the percentage reading stays artificially high while the actual cell voltage drops below what the system needs under CPU and display load. The laptop cuts power before the gauge reaches zero because the real voltage hits the protection threshold first. Run two full calibration cycles — discharge to hibernate, charge to 100% — and the fuel gauge IC will map the new cell's voltage curve accurately, eliminating the premature shutdowns.
