65 Wh lithium-ion replacement battery

This 65 Wh lithium-ion unit replaces the original BTY-M57 or 4ICP6/35/140 pack in compatible MSI GP66 and GP76 Leopard laptops. It delivers a nominal 15.2 V and is supplied new in black. Owners of listed models can restore factory runtime without adapter changes.

Direct fit for GP66 and GP76 series

The battery slots into the existing chassis bay using the original connector and screw points, so no extra cabling or mounting hardware is required. It frees the notebook from permanent wall-power dependence and restores mobile operation for the supported 10UE, 10UG, 10UH, 11UE, 11UG, 11UH and 12UGS model variants.

Steady output under continuous load

Lithium-ion chemistry maintains stable voltage during extended sessions such as gaming, rendering or video playback, avoiding the sharp droop seen in aged cells. The 65 Wh capacity sustains typical mixed workloads for multiple hours before recharge, and the pack is rated for a 12-month warranty period.
