Replacement battery for Surface Pro 7 1866

This KingSener G3HTA061H lithium-ion cell is a direct replacement for the Microsoft Surface Pro 7 1866 series. It restores the original 7.57 V, 43.2 Wh capacity so the tablet regains its factory run-time. The pack is supplied new and ready to install.

Thermal and power behaviour

The 7.57 V chemistry delivers the same voltage curve as the OEM pack, so the tablet's power-management firmware sees no change in load profile. Normal operation stays within the thermal envelope designed for the original battery, with no extra fan activity or throttling.

Fit and integration

The battery matches the exact mechanical outline and connector keying of the Surface Pro 7 1866 series, so it slots into the existing compartment without adapters or cable routing. Reusing the original mounting points keeps the chassis sealed and frees no additional space inside the device.

Questions about this item

How do I install the G3HTA061H battery in my Surface Pro 7 1866 and what step do people often miss?

Power off the tablet, remove the screen assembly, disconnect the old battery connector, fit the new 7.57V 43.2WH pack, reconnect the cable securely, then reassemble; the step most often missed is fully seating the connector before closing the device.

What maintenance or replacement will the G3HTA061H need over time?

The 5702mAh Li-ion cell will gradually lose capacity; expect to replace the battery again once run-time drops below your needs, typically after several hundred charge cycles.

What limit appears first when the G3HTA061H runs under sustained load?

The 7.57V 43.2WH capacity sets the runtime ceiling; under continuous high drain the pack will deplete before any thermal or voltage limit is reached.
