Replacement Battery for MSI GP66 and GP76

This lithium-ion pack is built to replace the original BTY-M57 unit in MSI GP66 Leopard, GP76 Leopard and Vector series laptops. It delivers 64 Wh at 15.2 V and suits owners of 10UE, 10UG, 10UH, 11UE, 11UG, 11UH, 12UE, 12UG, 12UGS and 12UH models who need a fresh power source.

Connector compatibility is the deciding factor

Factories vary the plug shape, cable length and physical dimensions even within the same part number. Before ordering, compare the product images with the battery currently in your machine to confirm the interface matches exactly.

Standard thermal and power behaviour

The 4280 mAh cell runs at the same 15.2 V as the factory pack, so heat output and discharge rate remain unchanged during normal use. No extra cooling or higher-wattage charger is required beyond what the laptop already provides.
