9-cell Li-ion replacement battery

This 9-cell lithium-ion battery replaces the original pack in compatible MSI notebooks. It delivers 11.1V and a rated capacity of 7800mAh or 87Wh for extended runtime. The black enclosure matches the chassis of the supported models. Condition is new.

Who this suits and who should look elsewhere

Owners of MSI GT60, GT70, GX780R, GX680, GX780, GT780R, GT660R, GT663R, GX660, GT680R or GT783R laptops needing a direct replacement will find this pack fits and functions as the original did. Buyers with other MSI series or non-MSI machines should look elsewhere because the connector and form factor are model-specific.

Deciding specification: 9-cell 7800mAh capacity

The 9-cell 7800mAh / 87Wh rating is the single figure that determines whether this battery meets your runtime requirements. Higher capacity than standard 6-cell packs means longer unplugged use, while the 11.1V output matches the system voltage exactly. Weighing .48kg, it adds minimal bulk to the listed GT and GX models.

Questions about this item

Will the BTY-M6D 9-cell battery fit my older MSI GT70 chassis without modification?

The BTY-M6D is engineered for direct compatibility with MSI GT60 and GT70 series models, matching the original form factor for a tool-free swap.

How can I verify the 11.1V 7800mAh battery is delivering its rated 87Wh capacity after installation?

Run a full charge cycle in your OS power report or BIOS health menu; the design capacity should read 87Wh and voltage 11.1V when the pack is new.

Does the KingSener BTY-M6D package include a charger or only the 9-cell battery itself?

The box contains the BTY-M6D 9-cell lithium-ion battery only; an AC adapter must be purchased separately if your original charger is missing.
