Questions about this item

How long will the 39.04Wh capacity actually run my Galaxy Book 12.0"?

The 39.04Wh pack matches the original Samsung specification, so real-world runtime will be the same as when the laptop was new — typically several hours of mixed use depending on screen brightness and workload.

Does the 7.7V rating limit which chargers I can use?

The 7.7V output is identical to the factory battery, so the original Samsung charger and the laptop's own charging circuit handle it without any adapter or voltage change.

Will this pack fit the XE310XBA and XE520QAB chassis without modification?

Yes — the EB-BW720ABE is a direct mechanical replacement for the listed Galaxy Book 12.0" and ChromeBook Plus V2 models, using the same connector and mounting points.
