Tryhi 9 Cell Laptop Battery 51Wh 10.86V 4730mAh

Replacement Battery for MSI Gaming Laptops

This 9-cell lithium-ion unit delivers 51 Wh at 10.86 V and 4730 mAh. It replaces part numbers BTY-M6H, 3ICR19/65-2 and 3ICR19/66-2 across a wide range of MSI GE, GP, GL and PE series notebooks. The pack is brand new from the manufacturer and rated for up to 500 recharge cycles. Buyers needing a higher-capacity pack or a different form factor will not be served by this model.

Build Quality and Daily Use

The black lithium-ion cells are housed in a rigid shell that matches the original battery footprint for the listed MSI chassis. No tools beyond a standard screwdriver are typically required to swap the old pack, and the connector aligns with the motherboard header without adapters. CE and FCC certifications confirm compliance with electrical safety and electromagnetic-compatibility standards. Users who prefer a slimmer 6-cell profile or an external power bank will find this internal pack unsuitable.

Practical Limits of the Chemistry

Lithium-ion capacity naturally degrades with each cycle, so runtime will shorten gradually over the 500-cycle design life. The 10.86 V nominal voltage is fixed; the battery cannot be used in laptops that require a different voltage rail. Capacity of 51 Wh sets a hard ceiling on unplugged running time regardless of power-management settings. Systems that demand more than 51 Wh per charge or a proprietary smart-battery protocol are incompatible.
