G3HTA048H 6800mAh battery for Surface Book 13.5-inch

This new lithium polymer battery replaces the original keyboard pack in Microsoft Surface Book 1 models 1703, 1704 and 1705. It is intended for owners whose built-in cell no longer holds a useful charge and who want a direct-fit spare without altering the device.

51Wh capacity at 8.7V

The pack delivers 6800mAh and 51Wh at a nominal 8.7V, matching the factory specification exactly. That single figure determines whether the replacement will restore the original runtime; if your workload demands more energy than 51Wh provides, this unit will not meet the need.

Includes tools, requires disassembly

One battery and a small tool kit are supplied, but no printed guide is included; the maker advises professional fitting or careful study of online teardown videos. The job frees the tablet portion from a dead keyboard base, yet it demands full keyboard removal and connector handling that less experienced builders may prefer to avoid.

Questions about this item

How long will the 6800mAh capacity actually run a Surface Book 13.5-inch keyboard base?

The 51Wh rating at 8.7V gives a practical energy figure; real-world runtime depends on workload, screen brightness and background tasks but typically reaches several hours of mixed use on this keyboard module.

Does the G3HTA048H connect through the standard Surface Book keyboard connector or a proprietary interface?

It uses the native keyboard-base connector built into Surface Book models 1703, 1704 and 1705, so no adapter or cable conversion is required for those units.

Will this battery fit inside the original 13.5-inch keyboard chassis without modification?

Yes, the G3HTA048H is shaped to the factory keyboard bay of the 13.5-inch Surface Book 1 and the package includes tools for the internal screws and ribbon cables.
