Screen Battery for Surface Book 1st

This lithium-ion replacement battery fits the display portion of the Microsoft Surface Book 1st generation models 1703, 1704 and 1705. It supplies 7.5V and 18WH capacity to power the tablet section when detached from the keyboard base. The cell is manufactured in China and supplied as a brand-new unit.

Sustained Use Behaviour

The 2387mAh cell delivers consistent voltage during extended screen-only sessions such as note-taking or media playback. Lithium-ion chemistry maintains stable output until the charge drops low, avoiding sudden shutdowns under continuous load. Capacity remains at the rated 18WH throughout the discharge cycle.

Installation Notes

The battery sits beneath the display assembly and requires careful disassembly of the screen module. Adhesive strips secure the pack, so a heat gun and plastic pry tools are needed to avoid cracking the panel. The connector is a fragile flex cable; misalignment during reconnection is the most common cause of a non-starting tablet.
