The NShi G3HTA061H is a new lithium-polymer battery built to replace the original cell in Microsoft Surface Pro 7 1866 series devices.

Suits owners of a Surface Pro 7 1866 needing

This unit fits only the Surface Pro 7 1866 series and replaces part numbers G3HTA061H and DYNM03. Buyers with any other Surface model, a different Pro 7 SKU, or a device that uses a different battery part number should look elsewhere. The battery is not compatible with Surface Pro 6, Pro 8 or non-1866 Pro 7 variants.

Voltage and capacity define the correct match

The replacement must supply 7.57V and 43.2Wh (5702mAh) to meet the laptop’s power-management expectations. Verify the original battery’s part number on the cell label before ordering; only an exact voltage and capacity match will allow the system to charge and gauge runtime correctly.

Questions about this item

How much heat or power draw does the 7.57V 43.2Wh battery add when the Surface Pro 7 1866 runs all day?

The 7.57V 43.2Wh lithium-polymer pack draws power only while charging; once full it supplies the tablet without extra heat from the battery itself.

What must I already own to install this G3HTA061H replacement battery?

You need a Surface Pro 7 1866 unit, the original DYNM03 or G3HTA061H battery to match the connector, and basic tools to open the back case.

Will this 5702mAh pack work alongside the original charging circuitry in my Surface Pro 7 1866?

Yes, the plug-and-play Li-ion design matches the factory voltage and connector, so the existing charge controller manages it normally.
