Replacement Battery for Galaxy Book 12.0

This new lithium polymer battery replaces the original Samsung EB-BW720ABE unit. It fits Galaxy Book 12.0" models SM-W720, SM-W723, SM-W727 and SM-W728 series. It also fits ChromeBook Plus V2 XE310XBA, XE350XBA, XE520QAB and XE521QAB series. Buyers with other laptop models cannot use this part.

Voltage Match at 7.7V

The battery operates at 7.7V, matching the factory specification for the listed Samsung devices. A different voltage would prevent the laptop from starting or charging correctly. Verify that the original battery label shows 7.7V before ordering.

39.04Wh Capacity and Cycle Life

Rated at 39.04Wh (5070mAh), the pack delivers the same energy as the original cell. It is certified for more than 500 recharge cycles over its service life. Heavy workloads that drain the battery in under two hours will reach the cycle limit sooner.

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.
