FAQ

Q: Is this the main battery for the Surface Book? A: No — this is the larger battery located inside the keyboard base. The Surface Book system uses two batteries; if your tablet unit won't stay on when detached, you likely need the G3HTA020H screen battery instead. Q: Does this battery fit the Surface Book 2? A: No — the G3HTA024H is specifically for the first-generation Surface Book 13.5-inch chassis; the Surface Book 2 uses a different battery with distinct internal connectors.
